China——The development of lithium power industry still need to improve grades

Posted by batterylhj on Thursday, November 05, 2009 9:40:33 AM
Lithium-ion batteries is ideal for a new generation of green energy, with a high specific energy storage, long cycle life, does not produce pollution, and so on. To produce lithium-ion batteries as the goal of lithium power industry in the world is in a good opportunity for development. Experts believe that China should seize the global opportunity for the rapid development of lithium power industry as soon as possible occupation of high-tech lithium-power industry high ground.
With lithium-ion battery production-oriented lithium power industry for nearly 10 years in the world to achieve rapid development in 2007 benefited from the renewed stability in the global handset market growth and consumer notebook drive, lithium-ion battery rapid growth in sales to approximately more than 30 billion only.
The layout of the global lithium-ion battery, Japan, South Korea and Chinese manufacturers dominate. From a technical point of view, Japanese companies are still a leading position, its high degree of automation production equipment, China and South Korea are from Japan, imported equipment and technology, through digestion and absorption, and then to constantly improve and improve. welcome to Dell Inspiron 640M Battery
Lithium-ion batteries in Japan, a huge domestic production in 2000, Japan accounted for 93.9% of the global market share of lithium power industry in 2002, has fallen to 67.4% in 2007, sales of Japan's global market share has dropped to 43 %, but the Japanese lithium batteries market sales still over 50% of the global market.
China is now the world's battery manufacturing power, the current battery production and exports are highest in the world, but China's lithium battery industry is only in recent years to grow up fast.
Lithium power industry of China began in late 1997, have gone through an independent research and development to learn from the introduction of the industrialization of the road. Entered since 2001, with the Shenzhen BYD, Banke batteries, lithium-ion battery company's rapid rise, China's lithium power industry has begun to enter fast-growth stage.
In 2007, China's production of lithium-ion battery has reached more than 1.4 billion, of which China's domestic manufacturers of lithium-ion batteries at about 1 billion or so, BYD company in the field of lithium-ion battery industry has entered the world top 5. In recent years, Chinese manufacturers of lithium-ion batteries worldwide market share stable at around 34%, and Japanese manufacturers of lithium-ion battery production in the formation of par trend. Acer Aspire 5610 Battery
At present, China has become the world's largest manufacturers of lithium battery production base, China's lithium-ion battery manufacturers in Guangdong, Tianjin, Shandong, Jiangsu, Zhejiang and other places. In 2006, the Guangdong region of the lithium production already accounts for 75% of China's industry, while the Shenzhen City the total accounted for 70% of the country.
At present, China has entered a self-contained lithium era of mass production capacity to rapidly grow, the price on the foreign brands have temporarily unable to match advantage. However, to ensure consistency in the battery, semi-automatic mode of production obviously can not match, and automated production. Therefore, the initial number of firms a foothold in the market, after spending a lot of money to introduce automatic production lines. In a highly competitive market, small firms will be eliminated within the next two years, and only the manufacturers of heavy weight also can be bigger and bigger.
At present, high-end lithium-power industry, the country's most enterprises are still in its infancy, as compared with the multinational corporations there is a great difference. Specifically reflected in the backward production facilities, products, poor regeneration, the lack of high value-added products and well-known brands to participate in international competition is relatively weak. Compaq Presario 2500 Battery
Therefore, the overall improvement of product quality and grade of a lithium power industry in China to expand its international market share in the key. The industry believes that the future development of enterprises in China lithium first market-oriented, technology innovation, relying on key research, development and production of high-tech high value-added small, lightweight, high-energy, non-polluting secondary battery. Government departments to implement policy guidance to promote the battery business investment and financing of multi-channel operation, adhere to the introduction of technology, equipment and digestion, absorption and innovation combine to encourage businesses to cooperate with the merger, sales resource sharing, reduce cost of sales.

5 techniques to change the world

Posted by batterylhj on Monday, November 02, 2009 9:06:32 AM

Who in these areas, if successful, would be like today's oil-rich country as to become the big winners in the economic field
This is an outrageous request: in the next few decades, the world needs to gradually free itself from dependence on fossil fuels, significantly reducing greenhouse gases. Current technology can only enable us to this point, we need to have a major technological breakthrough. These breakthroughs may be what? This article lists the five techniques, if successful, they will significantly change the pattern of the world's energy. These technologies can bring huge opportunities. For example, access to energy from space technology can quickly spawned a new industry. From the thermal power plant carbon dioxide capture and storage technologies may make more old power plant lease of life. Of course, these technologies are not necessarily successful, they are currently facing many problems, some techniques need to create in the lab or transgenic plant material and to achieve a number of major breakthroughs. Moreover, the cost of innovation can not let energy become too expensive. If we could do all of this, any one technology can change the rules of the game.

Space use of solar energy
30 years, visionaries have been envisaged in the sun to the place will never be able to shine use of solar energy in space. If we are able to orbit around the Earth placed a huge solar panels, will be in which even a small part of the available energy back to Earth, they can be anywhere on the planet to provide uninterrupted power. The technology may sound like science fiction, but in fact very simple: in addition to 22,000 miles of solar panels in the form of microwave energy back to Earth, and then converted into electricity and into the power grid. (Low-energy beam is considered safe.) Diameter of 1 mile of the ground receiving station can provide about 1,000 megawatts of electricity, enough to supply an average of about one million U.S. households use. Solar collector sent the cost of space is the biggest obstacle, it is necessary to design a light-weight enough, can reduce the number of launches that system. Some countries and companies have been early in the next 10 years, hopes to provide such space power.welcome to Apple A1078 Battery

Advanced Automotive Battery
Electric vehicles can reduce oil consumption and help the air cleaner (if the electricity comes from wind energy and nuclear and other low-carbon fuels it). But it needs to use better batteries.
Commonly used in notebook computers is the next generation of rechargeable lithium-ion battery-in hybrids and electric vehicles of choice. They car battery power than other more abundant, but also more expensive, but the charge was still far enough away from the road; will be listed next year, Chevrolet (Chevy) Volt hybrid With battery is about 40 miles drive. Ideally, the best way to be able to charge electric vehicles travel nearly 400 miles. Although there is still room for improvement, but the potential for lithium-ion battery is limited. As an alternative product, the performance of lithium-air batteries, lithium-ion batteries 10 times, can provide the same energy and petrol. Lithium-air battery to absorb oxygen from the air charging, so the battery can be smaller, lighter. Many labs are experimenting with this technology, but scientists believe that if there is no major breakthrough, in order to achieve the business may also need to 10 years.

Power Storage
All in support of wind and solar technology, how can you stay out of? While wind and solar energy is that either the use or loss of resources. To change the status quo, they need a better storage technology. Scientists are a lot of perspective from the response to this problem, but face challenges in all aspects. For example, a technology is through the wind to compress the air inside the underground caves generate electricity; to air transport to the gas turbines to improve combustion efficiency. Of which face an obstacle: to find a large space and the available underground caves.come here TOSHIBA PA3178U-1BAS Battery
Similarly, there are able to absorb the wind energy to be future use of the huge battery, but some of the current and costly technology, other technologies are not very efficient. Although researchers are looking for new materials to improve performance, but to any significant technological leap is unlikely. Lithium-ion technology may be the best prospect of grid storage technology, the technology in this area do not face as in the automotive industry as many restrictions. With the performance and price reduction, public utilities may be the edge of the grid, the more close to the user's local transport small high-capacity lithium-ion batteries. Thus, these lithium-ion batteries can be stored in excess of renewable energy sources of energy, will help stabilize the electricity supply to the small fluctuations, improving the efficiency of the grid, to reduce the standby power plant needs. Utilities can use the car battery research.

Carbon capture and storage technology
That the average human emissions of 30 billion tons of carbon dioxide per year, resulting in a serious greenhouse effect and environmental pollution. Human emissions of carbon dioxide, the main way of fossil fuels, land use and deforestation. Of these, 40% from power plants, 23% from the transport sector, 22% from cement factories, steel mills and oil refineries. Effective use of carbon dioxide, the greenhouse effect can not only reduce the threat to humanity, but also an enormous economic benefits. Continue to coal as a main source of energy implies the need for efforts to reduce the carbon dioxide generated by burning. This may mean building a more efficient new power plant. However, the current power plant to capture carbon dioxide (approximately 20 million tons) could be a truly game-changing technology. At present there have been small-scale carbon dioxide capture technology, but if these technologies for large-scale power plants will lead to reduction of one-third of generating capacity and resulted in cost of electricity has doubled. Thus, scientists are looking not only be able to reduce carbon emissions by 90%, but also limit the cost of growth in experimental techniques. Almost all technology, are currently at a preliminary stage, which method can now assert that the ultimate winner is premature. The Obama administration has begun will be "carbon capture" clean coal included in the recommendation a key element in plans to invest in the next 10 years, 450 million U.S. dollars to 7 carbon capture and sequestration project experiments, supporting many of the areas of research and development, including thin film technology, phase separation, catalysis capture technologies.
A promising technology is based on metal oxides in the form of burning coal and pure oxygen, rather than burning in the air, this method will produce easier to capture carbon dioxide concentration of air, almost does not affect the power plant efficiency. This technology has been in small-scale pilot projects carried out show next year will be used for an installed capacity of 1 million watts of test plant. However, by 2020, this technology may also be difficult in commercial use.look FUJITSU Fpcbp77 Battery

The next generation of biofuels
We are a progressive way to get rid of its dependence on oil is to develop a renewable transportation fuels. This means that from the non-food crops, developed a new generation of bio-fuels.
The researchers are now looking for a way to wood, crop waste, garbage, and switchgrass and other non-edible plants into fuel have a price advantage. However, the most optimistic about the prospects for a new generation of bio-fuel from algae. Such micro-organisms can not only remove the air of carbon dioxide, but also to rapid propagation - some species will be able to use only 12 hours to double, while the grass and other large-scale plants will need several weeks or even months to reach such a level. Photosynthetic micro-organisms inside the cell can store large amounts of fat, which is the basis for the synthesis of bio-fuel raw materials. One acre of algae can produce more than 5000 gallons per year of bio-fuels, while an acre of corn can produce 350 gallons per year of ethanol. Algae fuel can be directly added to the current refining and distribution systems. Theoretically, the United States can produce large amounts of algae fuel, enough to meet all U.S. transportation needs. But now is premature. Dozens of companies have started pilot projects and small-scale production. But the mass production of algae fuel means to find a reliable, inexpensive nutrients and water resources, control of pathogens could lead to cuts, R & D and foster the highest yield of the algal strain.
If you look at history, we know that "anything is possible" is very justified. There was also a lot of people think that human beings can not fly in the sky, it is impossible to walk on the moon, light bulbs can not be light-emitting ... ... fact, human beings need is a multi-disciplinary collaboration. No matter who, as long as mass production of bio-gasoline, then he received large sums of money that will not only will make history. To some extent, the future, if some countries or large companies can be successful in this regard would be like today that the oil-rich countries, to become the big winners in the economic field

China in the future of the seating B2C race has begun

Posted by batterylhj on Saturday, October 31, 2009 6:12:21 AM
If you hit start to the rise of online bookstores, B2C in China for 10 years. On the Internet for a decade was a very long period of time, ten years enough to eliminate a business, is enough to success of an enterprise. To B2C, the smash hit of 8848 ten years ago, Albemarle sort of B2C Web site, and now has become history, while there are a number of westbound who finally achieved after a decade of hardships and dangers of the Scriptures, Dangdang is one of them a representative. Ten years ago, started from a low-priced books Dangdang, and now is no longer a single-line bookstore, but transformed into an online retail, on millions of products online mall, and in March this year to become an Internet "profit club" in the 1, which B2C China as a whole is truly is the first time. Profit possible - This allows the industry's confidence can be regarded as playing a shot in the arm.welcome to Dell Latitude D600 Laptop Battery.
Not long ago, for an extension of Dangdang to the mall, it was said, Dangdang missed the most crucial years of the development of department stores, some people do not think so. Over the past nine years, the domestic environment, they can only support the entire e-commerce from online bookstores such as product differentiation is small, price is low, after-sales service simple, safe and convenient transport of goods, in addition to books, other department store household goods in the net the environment is not ripe age of purchase is not appropriate. In the past year, online shopping department store for more than a larger market for transit, it is thanks to online shopping is increasingly being accepted by all, and the related services and transport have been greatly improved. "At the right time to do the right thing." So, started early and is not necessarily a good thing, Dangdang from 2005 onwards a gradual expansion of the department store, I think it is appropriate measure. Consumers accustomed to cultivate the market also needs a warm, otherwise, can not become a pioneer, but will become martyrs. Although the martyrs is worthy of respect, without them, market maturity will slow the pace several times, but many people believe that companies are willing to be martyrs do not have a bar!
Dangdang involved in B2C from ten years ago now, there is no reason as to become martyrs, like 8848, but China's B2C side of flag, perhaps due to its stable of market expansion strategy, due to Dangdang scale expansion of 10 to keep the purchase cost, warehousing costs, logistics costs and other operating cost advantage. Although retail is a low-profit industry, but the advantage is that the size of the retail can be done very large. The need to do a large scale, we need ever-expanding category, to penetrate the upper reaches. In order to scale, after several years, Dangdang has been carrying out horizontal and vertical expansion, such as the involvement of the upper reaches of audio-visual products and books for OEM customization and distribution, extended to products other than books category, try a joint venture investment model Mall. you will know more to Compaq Presario 2100 Battery
As other companies in the world, like the value of intangible assets is much higher than the value of tangible assets, Dangdang development today, the most valuable is not the sales from 2 billion to become 10 billion, but a cause of an average consumer those who trusted brand. The Nielsen data released a few days ago, then just to prove Dangdang brand advantage. Nelson, the city bought in 2009 net transfer showed that "China's netizens shopping site for the cognitive case, in the absence of prompt recognition and general awareness of tips case, Dangdang respectively 54% and 93% ranked B2C shopping site first. B2C shopping site in the users browsing behavior research in the last three months of the respondents viewed Dangdang ratio to 48%, ranked No. 1; 75% of the respondents had been browsing Guo Dangdang. In the B2C shopping site to use for the user behavior (ie, purchase behavior) research in the past year used Dangdang B2C customers ratio to 38%, while the frequently used Dangdang the percentage of users has reached 26%, The two indicators of all B2C sites were ranked first. "
Cheap and integrity has always been that all B2C companies must adhere to the two concepts, while the addition, there is an increasingly important factor, which is service. To Dangdang and Taobao, the two representatives of B2C and C2C examples. With Taobao different Dangdang practice is to select the right product for the customer, thus saving the customer both good and bad in the mass of goods in the selection of time and energy costs. Dangdang require not only inexpensive, but also services in place, to the customer select the right merchandise, it is Dangdang model. The Taobao selling point lies in smart consumers to cheaper Amoy, Amoy was inexpensive, but for the viewer is not the point of smart buyers do, buy a notebook computer Hom of 200 money, full of joy of the receipt of goods, The results showed that the battery is produced domestically, a little cheaper nor Zhan Zhao. Amoy fun smart person, most people Amoy hard. look Fujitsu Lifebook t4010d Battery
Also B2C, the different games are played also determines the realm of high or low, the size of the results. For example, Amazon is a great multinational corporations how to play, he would like to profound knowledge, the best back-office systems, the best luxury group, but in the local procurement costs a lot more backward than Dangdang, and can not afford price war Dangdang . As we all know, size and procurement cost is inversely proportional to the size of the larger, lower procurement costs, while the lower procurement costs, lower prices, the scale also faster growing. This cycle of growth and Dangdang, compared with the procurement excellence should not have cost advantages, the scale is now getting smaller and smaller, not to mention a weak economic foundation and thick, so as to such a trend continues, the result was naturally self-evident a.
Ereli noted that the recent advisory issued by "iResearch-B2C e-commerce website market impact assessment study report", the report shows, Joyo to 380 overall score ranked second, Jingdong Mall Zeyi ranked 379 overall rating Third, while the Dangdang to 389 overall rating topping the list. At the same time the first half of Analysys International data show that Dangdang covering 32.9% of China's online shopping market of users, is covered by the user the most B2C firms.
A consensus that China's B2C online retail market at this stage and its future development will focus on the 3C and the department store market. I think that the next decade, department stores and online retail rivalry, will determine China's B2C online retail supremacy seating, while the industry reshuffle will also be launched.

From luggage to a small pocket——notebook

Posted by batterylhj on Monday, October 26, 2009 9:59:21 AM
Darwin's theory of evolution, the survival of the fittest is its point of view, when large dinosaurs have ruled the Earth, but with climate change, everything has changed, and these big guys have become a fossil, and we rule the world. Today we will take everyone to take a look at a number of years before "notebook computer" then do not even have color monitors, notebooks from the huge, expensive synonymous has become today's portable, cheap, during which after a very long period of time, those great shape The notebook, and today seems no doubt that, like dinosaurs, and you definitely will not be second-hand market to see these things.
Today's notebook and desktop computers already have similar performance, but also in the generic basically the same, and now the notebook in the portability and performance can be regarded as impeccable, while the appearance on the laptop products and individuality are increasingly the pursuit of exquisite Delivery; as 30 years ago, NASA and the military made the beginning of this idea of portable computers, those big ugly performance notebooks in general, after so many years of development has been completely reborn in. know more to Dell INSPIRON 9300 Battery

1970-1981: the beginning of portable computers
Words in the long, long time ago, the idea of laptops from a person named Alan Kay, who work at Xerox, in the twentieth century, the seventies, when he came up with this idea, the old chap and even his ideas published.
Will soon have the company used his ideas are currently recognized by most people, like, the first laptop was Osbome 1,1981 by Adam Osborne Chupin, something that the entire weight is 11 kg, is basically a sack of rice or less. If this news has shocked you, here there are other, this product is 5-inch display. Would like to take this thing everywhere, you need the strength ...

1981-1984: IBM's rise
Although the broad masses of ordinary users to IBM know that from the small black notebooks start, but early in the eighties, IBM has already begun to join the cause of the laptop. However, when many utility companies to join the laptop are now concerned about the degree is not high, Gavilan introduced models that year, it had already some are like the notebook, and clamshell design is quite pretty trendy. That year the company introduced the weight of just 4 kg, the battery can be used time to reach 9 hours, know that it uses is? Nickel-cadmium batteries ... but look at the screen to know, and everyone seems to use the calculator almost, as well as the first division of the Laptop to laptop computers in this category is the Galvin Corporation.
The development of the Osborne 1 portable computer company, then this is certainly a huge potential market, Microsoft also get involved with this year, Radio Shack TRS-80 model 100 this product is to use Microsoft's text-editing software, machinery and use of LCD screens, bring their own modem, you can send some text.
When the Radio shack began to set foot in this market, when, IBM's products were first introduced, 84 years, PC5155, this product again back to the original portable notebook old.welcome to ACER Aspire 3200 battery

1984-1988 Compaq into the notebook market
Compaq, is a company that was acquired by Hewlett-Packard, when regarded as wasteland when the definition of major companies are not the same notebook, what kind of shape it is strange there, Compaq introduced a 88-year SLT 286 has reached 640 × 480 resolution, this laptop has 1.44 inches of floppy drive interface, the whole weight of 6 kg, the machine also VGA output.

1989-1993 NEC into the line, the first Apple laptop
Japanese firms began to set foot in the notebook industry, NEC out is the introduction of the lightest notebook computer, you can completely run the MS-DOS computer, the machine weight is 1.99 kilograms, and today's notebook has almost the same. When 89-year, Zenith introduced a machine with 640KB of memory, 1.44-inch floppy drive, as well as modulation and demodulation as well as the 20M hard disk, as well as color display.
Apple is also entering the market that year, are now referred to as MAC and the full name is Macintosh, laptop was called the Macintosh Portable, the weight to 8 kg, has a very high-end time to 9.8-inch display, resolution of 640 × 400, and even rolling track ball, the next time, Apple's graphical interface operating system, so that everyone is very interested in the subsequent 93,256-color Apple PowerBook 165C notebook now has been quite the same again. The machine has a floppy drive, but then the price of products still can not give a lot of people to accept, or a small number of business people's top office equipment only.look!

1996-2003: Panasonic military books and Intel processors,
96 years, Panasonic introduced the Toughbook (CF-25) a drop from 70 cm height of the notebook is not broke, dust-proof waterproof, Matsushita's products is absolutely prepared for the development of new markets, such as the military market, which product to use a large number of metal. By 2003 with the Pentium M processor, the emergence of a large number of low-cost laptop market, a few hundred dollars of products into the mainstream, notebook product is no longer the choice of high-end business people, but rather the civilian-oriented products, especially post-secondary students in institutions, to facilitate the learning and entertainment, notebook is their good helper.

Today's notebook

Today's notebook products, wireless, 3G are the keywords, as well as Blu-ray drive, advanced graphics, as well as wide-screen portable, all so that the first laptop Osborne 1 looks like a useless monster. More beautiful and cooler notebook products more and more. In 2007 started the wave of the Internet, has even more original high-priced notebook market segmentation thin and exhausted, is mainly used to access these small, in fact undertake more work, in addition to 3G network, you can in the coffee shop of the class where the Internet.
In addition, the notebook will be more in the future direction of development is thin in one direction, the performance is another direction, there are still a lot of special products, such as dual-screen laptops, multi-touch, as well as gesture recognition, as well as thinner OLED technology.

The future of laptops

20 years ago, we look at Apple's MacBook Air certainly think that it is science fiction, but today it really occurs, and the future will be like?
Holographic technology, laptop computer, no screen, direct projection in the air, a strong touch technology, like many years ago to see the laser keyboard, as well as fuel cells, may give a laptop the same as the calculator, for a long time do not have to charge.

Home Wireless Network Outlook

Posted by batterylhj on Saturday, October 17, 2009 9:30:01 AM

Home wireless networking is heating up, home wireless networking products, a good day is coming.

?Wireless market, how much??

With the continuous improvement of living standards of the general public, with two or more PC's family is already very common, and some families as many as 56 laptops plus desktop platform. In the past, the main form of home computers are desktop computers, and now, many families in addition to desktop machines, but also acquired a laptop, PDA, DC, or DV, through your home wireless network to connect these products can not only enjoy at home wireless networks fun, but also lifted the impact of indoor wiring, as well as beautiful, and many other troubles.know more to IBM THINKPAD 390 SERIES Battery
Past two years, Internet access fees continue to go down 100 yuan on a monthly unlimited broadband, has been popular in many cities and regions. Therefore, the home wireless LAN needs are quietly growing and will form one of the most growth potential large market.

From the U.S. market, the news showed that with the increase in U.S. broadband access users, home digital network market offers enormous potential for development. In 2002, the U.S. sales of digital home networking market reached 3.7 billion revenue is expected to in 2006 that the business will bring about 7.5 billion U.S. dollars of the sales market. According to Gartner Dataquest's sake survey WLAN sales in 2002 increased by 73% to reach 2.1 billion in sales in 2003 will grow to 28 billion U.S. dollars, and this high growth trend to continue at least until 2007. In China, the home wireless network is the status? Consumer awareness in this area and the market demand for their services? National survey of an institution is given a detailed data.

The future network trends: wireless networks accounted for 81%, cable networks accounted for 13%, he could not account for 6%; users knowledge and understanding of wireless networks: Understanding accounted for 69%, 28% would like to know, are not interested in 3%; are most concerned about wireless network standards: 802.11b accounted for 24%, 802.11b + accounted for 17%, 802.11a13%, 802.11g3%, Bluetooth accounted for 24%, HiperLAN2 3%, home networking, 16%; restricting the development of the wireless market, the main factors: accounted for 64.15 percent product price, product performance, accounting for 25.47%, 9.43% vendor services, use the difficulty of accounting for 0.94%; can accept a wireless card price: 500 yuan accounted for 83% of the 500-800 accounted for 12% ,800-1000 yuan accounted for 4%, more than 1,000 yuan accounted for 1%; an acceptable price of a wireless access point: 1000 yuan accounted for 69% ,1000-1500 yuan, accounting for 25% ,1500-2000 yuan, accounting for 6%, 2,000 yuan or above zero.look Apple A1079 Battery

The answer can be seen from the above, the price is a major constraining factor in the development of wireless networks (64.15%), 500 yuan a wireless card, less than 1,000 yuan a wireless access point is the average consumer can accept the price. However, 81% of the prospects for wireless networks, which indicates that the potential market for wireless networks is very promising. The key is that companies can and when the price of wireless networking products down, down to the public generally acceptable rate? With the advantage of gradually emerging wireless networks, wireless networking products will be into more and more ordinary families.

?Network Products Color??

Home wireless network is wireless Hub (wireless hub), Wireless Access Point (Access Point, AP, a network bridge-pass device), wireless bridge, wireless Modem and wireless network cards and other products to form, some of the wireless way by the device combines wireless bridge capabilities, and some can also be made to talk about the wireless Modem wireless hub (Hub), of which the most widely used wireless network card, use was also up. In the wireless networking market, for many years been dominated by foreign brands in recent years, some domestic manufacturers have joined the wireless networking products to compete on prices caused some impact. With Cisco, Intel and other giants of the increasing popularity of 802.11a equipment, wireless network card, wireless access point prices decreased significantly. According to available market quotations IT168, many brand-name wireless card dropped thousand dollars less, and some have even dropped to three or four hundred yuan, Five, six yuan price of wireless cards available for a great choice. Around 1,500 yuan increase in the number of wireless access points, many products had fallen to 1,000 yuan. Gradually formed the pattern of competition in the market, wireless network equipment price war is inevitable. In 2002, as a home wireless network, one of the main products, Bluetooth products have sprung up, Apple, Epson, Palm has introduced a Bluetooth adapter, etc.; IBM chips into mobile phones via Bluetooth into a notebook PC remote control; micro - Star launch of the Bluetooth board 845E MAX2, for the Bluetooth card, Bluetooth Modem provides a handy; Fuji released a Bluetooth module inside the plant, and a modem to connect to the Internet in the new Pocket PC, Toshiba introduced the wireless home entertainment network among the plans to introduce a new chip based on the 802.11a standard, embedded in TV sets, stereo, DVD and notebook computers and modems and other equipment, that could be achieved using wireless information exchange, creating a radius of 90 meters of wireless LAN, per second data transfer rate of about 54MB.come here HP Pavilion DV4000 battery

Intel PCA to promote seamless roaming wireless network

Posted by batterylhj on Saturday, October 17, 2009 9:01:10 AM

A wireless network in the world are already visible. We are trying to connect together a truly wired and wireless networks become a global player, and now wherever they are to maintain personal or business ties have been possible. However, neither the user or the service providers are still some needs are not being met. Mobile users want fast Internet access and seamless roaming capabilities, their use of equipment without complex settings, enter the authentication parameters, adding and changing user preferences, update phonebook, as well as from multiple service operators received bills and so on.

On the other hand, service providers need new sources of revenue. The previous wireless service revenues mainly come from the expansion of coverage and the number of users increase. However, voice services, as competition intensifies has become a common commodity, and the results from the average revenue per user continues to decline. This revenue source has been its high-growth period, and has not enough to build 3G infrastructure and access to new frequency bands to provide adequate financial support. The 3G technology will provide opportunities to develop new services for service providers to create new revenue streams. Fortunately, users seamless roaming and authentication, and can easily be set up to increase demand and service providers attempt to coincide with new revenue. New revenue from new services, but these new services require new technology to simplify the equipment set-up and certification process in order to achieve more convenient and seamless roaming. come here FUJITSU Fpcbp95 Battery

The ideal model of seamless roaming

Intel's vision of the wireless device usage patterns allows users on different networks using a variety of handheld devices to achieve seamless roaming. As a result, with a GPRS enabled mobile phone, PDA and notebook PCs will be able to WLANs ? wireless LAN and WWANs ? ? ? wireless wide area network freely roam and communication, and can be connected to the Internet. At the same time, in different client authentication between the device and network management tasks ? often require multiple registration name and password ?, as well as the associated user equipment and a variety of settings and parameters configuration would be an automatic and invisible process, rather than let the user to worry about. This is a matter of great yearning for the ambitious goals, to achieve it needs to do a lot of work in many areas to promote
Technological development, including the IP address management consolidation mechanisms, such as: mobile IP, billing management, and roaming services, wireless technology and security protection, and so on.

Wireless Technology Development Status

There are a variety of WLAN standards (IEEE 802.11 which is the most popular) and a variety of WWAN standards (including GSM / GPRS, CDMA2000 1XRTT, CDMA2000 3XRTT and W-CDMA, etc.). Some use different radio technology, all of the standard have adopted a different communication protocol. In the WLAN in, IEEE 802.11's status has been established and has achieved rapid development. It is through a different wireless technologies were at different frequencies and use different modulation schemes are defined to run multiple physical definition. However, in most cases, although the agreement itself is constantly changing and strengthening, it is all the physical layer defines the standard protocol used.
In the WWAN, with the entire industry, the transition from 2G to 3G, using the IP data packet transmission data services are gradually achieved, and will eventually become the 3G technology. Here, a variety of standards have a different definition of the physical layer. In the GSM, based on, 2.5G services, mainly in the form of GPRS and EDGE ? GSM to enhance data transmission ?; Similarly, CDMA technology is upgraded to a 1XRTT ? One Times Radio Transmission Technology ? or CDMA2000 1X ? order to provide similar data services. With GPRS and EDGE upgrade to WCDMA, 1XRTT upgrade to 3XRTT, 3G services will provide higher data rates.

GSM networks use SIM technology to achieve authentication between networks. SIM technology is also being applied in a number of competing certification WWAN technology, WLAN and WWAN networks is expected to become a bridge between the certification. look HP Pavilion dv9000 Battery
SIM Authentication Technology

Intel envisages the use of SIM authentication technology to develop an ideal roaming mode, the software SIM module is expected to be applied. This model provides the user with more flexibility, and to the back-end servers to minimize impact. SIM can be completely stored in the software, so do not use the dongle to save the SIM card. Virtual SIM card has several advantages. Users do not need to worry about the physical form of cards, save, remove, and insert the SIM card and battery case brought by the demolition of the problem no longer exists. The new device can be loaded into the user's SIM information software and easily complete the set up process. However, the concept of a virtual SIM to be a very safe way to implement, and provide the same smart card security. Certification must be in a protected storage space to carry out, without outside watching for. Authentication and encryption protocol must be carefully designed and uses the industry proven standards of public safety algorithms.

Client devices using Bluetooth technology transfers between SIMs

Advantages of using Bluetooth-enabled can be automatically and invisibly to provide services to locations, individuals can find a virtual SIM, and from another device (via permit) to take it over. With a Bluetooth-enabled devices can be with another Bluetooth device in a small wireless personal area network WPAN ? ? on communication. When the Bluetooth devices close to each other to some extent, the Bluetooth network will automatically form, so that the Bluetooth device discovery services and share information.

Intel PCA to prospect a reality

Intel PCA ? Intel Personal Internet Client Architecture ? through the communications tasks and processes separated from the application processing to accelerate the seamless roaming for new applications innovation. As PCA Development Kit part, Intel is for service and client hardware development standard building blocks and API (application programming interface). Developers can use the future building blocks to implement tasks such as roaming and virtual SIM. By allowing developers to use the SIM for roaming and authentication, open the way to a new, rich applications and services to the door.know more Compaq Presario 1200 Battery
Intel PCA allows developers to boldly Fantasy next-generation wireless applications, without having to worry about from one device to another device, from one network to another network incompatibility issues that occur. Intel PCA using a virtual SIM-compatible applications will be through a robot, and new services to users of the exciting new features. These new applications for wireless service providers to bring new growth opportunities and meet customers in today's wireless world of convenience, security and freedom of desire.
The wireless world is rapidly formed. For wireless roaming across the network gave birth to the growing demand for new technologies to simplify set-up and certification of equipment to enable seamless roaming possible. Some techniques can make the ideal become a reality, many of which are facilitated by Intel PCA. By allowing developers to use the SIM to achieve roaming and authentication, many new applications and services will be possible.

Five new system and new configuration of Notebook

Posted by batterylhj on Sunday, October 11, 2009 9:47:44 AM
Aspect One: The popularity of high-end single significant
In recent years, DIY desktop PC market growth slowing, then the notebook market was the explosive growth of the domestic tens of thousands of DIY users to purchase their second or third computer, we will consider switching to notebook camp. But the problem is that most international manufacturers such changes to domestic consumers has been insensitive, has not been introduced into mainstream price points significantly to this high-end alone, resulting in the potential of this part of the user's consumption can not be released. Of course, the heat dissipation problems are another reason leading to this situation.
In fact, the international manufacturers failed to grasp the changes in the China market is also reasonable, because in the United States and Japan, these developed countries, many people are using PS2 and XBOX, or Alienware laptop play games such a big-screen, 13 ~ 15 -inch notebook Zeyi set, which mainly focus on portability, thermal effects and life time, so as the U.S. Hewlett-Packard, Dell and Apple, as well as Japan and South Korea's Sony, Toshiba and Samsung, these manufacturers did not have any this year, too the mainstream size in the high-end multi-alone significantly to this. for more information to Sony VGP-BPS3 Battery
First discovered the potential market is a piece of China Taiwan's two major manufacturers: Acer and Asustek, which in recent years has introduced an exciting game notebook. They continue to launch driving down prices, also in bold and innovative designs, such as the Acer 5935G, Asus N51Vn and so on, once the Asus G1 and G2 gaming remember this is also a cause.
But starting this year, there was finally the hang of a few companies, has introduced affordable high-end single remarkable book, such as Lenovo Y450, seven-V98, Samsung R518, and the Shenzhou-HP860, etc., of which the best performance of the card is GT240M and HD4650 (GDDR3 memory). In addition there is news that Sony will soon release a new 14-inch, using GT230M graphics, the same 48 stream processors and 128bit memory interface, and is equipped with GDDR3 memory, core frequency is only slightly lower than the GT240M only , the performance gap is 10%.
Obviously, who can accurately grasp the characteristics of Chinese consumers, who will be able to occupy the fierce market competition advantage, with the process of constantly updated in the future notebook graphics cards heat will be getting smaller and smaller, in the 16-inch notebook using GT280M The top card is nothing difficult, as long as the heat clearance, the price is reasonable, we will certainly have a lot of consumers to foot the bill.

Aspect 2: Core i7 quad-core more "smart"
In the September meeting of the 2009 Fall IDF, Intel officially released the mobile version of Core i7 series quad-core processors, and the old quad-core than the Core i7 There are five-point improvement: 1. Core-frequency acceleration. 2. Hyper-Threading Technology. 3. 3 up to 8MB cache. 4. Integrated memory controller. 5. Built-in SSE4.2 instruction set.
After the release of the new processor, the major notebook manufacturers have also introduced the corresponding quad-core notebook. While the mainstream consumer does not need such high-end products, but there was still a small number of customers are seeking better performance, such as professional graphic designers, video editing, etc. workers.
As the first use of the mobile version of Nehalem architecture processors, the Core i7 give us the impression that "more intelligent of", it can be more flexible allocation of resources and energy consumption, thus achieving high efficiency, as much as possible to reduce fat heat, and to extend battery life. At this stage 15 to 16-inch laptop can easily be up to them. look you enter a wonderful place Dell Inspiron XPS M1710 Battery

Aspect 3: CULV be made dual-core power
For ordinary users, the current high-end processors, there have been performance, surplus, so the industry generally believe that a low-power processors will be another future direction of development. In the past two years, the Core 2 Duo U Series processor is the balance between performance and low power consumption model, appears in a small number of ultra-thin notebook, by virtue of heat is small, the advantages of long life Beishou business people of all ages However, due to high prices it is difficult to be accepted by the consumers at large.
Starting in April of this year, cut half of the core of the single-core CULV (Consumer Ultra Low Voltage, consumer ultra-low voltage) notebook market, and at first it is due to thin and light portable, affordable and high degree of attention, but soon found that users kinds of low-frequency single-core processor (eg, SU3500) has been unable to meet the needs of mainstream applications, so their enthusiasm quickly cooled.
The evaluation under long-term experience, we believe that: Pentium dual-core processor is the most cost-effective, while the dual-core CULV is thin and light notebooks running mate. Prior to the high prices are impeding CULV dual-core universal barriers, and as SU7300 and SU4100 and its follow-up models listed, those who complain about laptop battery life is too short, and the limited budgets of consumers can finally satisfied.

* Aspect 4: Ultra-thin design to solve the whole problem
Rely solely on the popularity of dual-core CULV parity, but also not enough to fast-growing ultra-thin and light notebooks, while other technologies continue to make breakthroughs and mature, so that the rapid decline in the overall cost is the cause of this emerging market is the direct cause of growth spurt. These technologies enable thinner and lighter notebook mainly in the following three points: 1. LED backlight technology. 2. Lithium polymer batteries. Lithium-polymer battery (Li-polymer, also known as lithium polymer batteries)such as IBM Thinkpad X40 Laptop Battery can be done very thin, and the shape of space can also be determined according to the bottom of the notebook, which greatly reduces the difficulty of ultra-thin and light notebook designs. And the former compared to lithium-ion battery, which uses the colloidal solid, so there is no leakage problem; but also in terms of capacity, it will more than the same size lithium-ion batteries twice. 3. Even smaller chip manufacturing process.

* Aspect 5: Window 7 for books easier to use
In the past, the introduction of next-generation operating system, might trigger a wave of PC upgrades, but this time, we believe that this situation will not occurred on a scale that is at most a part originally intended to 8,9 shot on consumers, may be because of Win7 and wait until October, after all, the direct than indirect upgrade pre-installed to save trouble, rest assured more.
In the current view of the industry comments, we generally agreed that Vista is only a transitional product collection issues, while the Win7 is the next-generation operating system, the final shape, in terms of speed, aesthetics and ease of use have better performance, although they There are some small Bug, but at an acceptable range, just as XP just the same as when it is published. We have a trial after its taskbar preview feature impressive.

iPhone replace the battery on their own income users can not replace

Posted by batterylhj on Friday, October 09, 2009 7:50:37 AM
Chinese companies issued for the Apple iPhone, how to replace the battery matter, insiders said that this was mainly due to the specially designed iPhone mobile phone battery, users can not replace the battery on their own, as to change a battery 710 yuan if the price is reasonable, it is impossible to say clear, but Apple's advance notice is the right move.


iPhone replacement battery cell phone users can not self -

Prior to the July 8, Apple China published in Chinese information, saying that "if the iPhone, only because the battery capacity of rechargeable batteries to reduce the need repairs, Apple could help solve, but the iPhone, when you will be in maintenance fee." welcome to Dell Inspiron 6000 Battery

The service should be targeted at China Unicom version of the iPhone. Apple's published information on Chinese companies explained that the result of accidents or damage caused by improper use of iPhone, not entitled to this service.

At the same time, Apple warned that Chinese companies, repair process will erase all data on the iPhone. Please sync iPhone with iTunes to back up the address book, photo, e-mail account settings, text messages, and more, it is very important. If the repair process of loss of information caused by iPhone, Apple is not responsible. In addition, Apple does not provide any data transfer services.

In this regard, there are familiar with the iPhone in the industry said, iPhone mobile phone battery problem is an old issue, which was mainly due to a special iPhone battery design, the user can not on their own replacement battery, if the batteries wear serious, would need to be sent to the Apple repair .

Advance notice to replace the battery once a charge 710 yuan

Apple said the Chinese company's information, the above battery replacement cost, including taxes and fees, including a total of 710 yuan. look ! ibm Thinkpad T61 battery

With regard to the cost is high or normal, this does not make it clear that because of Apple's products are always expensive, for example, an Apple wireless keyboard to be 628 yuan, while the Dell's wireless keyboard is also as long as more than 100 yuan; an Apple remote control and microphone functionality -Ear Headphones have 628 yuan, but actually a very stylish Motorola headset as long as more than 100 yuan; an Apple LCD computer monitors to 7998 yuan, than most brands of laptops are more expensive.

Prior to that, in the United States, there have been a user complained to the Federal District Court in Oakland, California, the indictment says iPhone battery charge-discharge after about 300 had been scrapped, a battery usage time is usually less than a year.

Apple on its Web site later opened a special column that tells consumers how to extend iPhone battery life. "If you properly use and maintain, an iPhone battery after 400 full charge-discharge after the 80% of the electricity still remain," Apple's Web site claims that "if the battery is fully charged the battery can not meet the needs of the time, you may consider replacing the battery such as Acer Aspire 5620 Battery . "

Complaint also said, iPhone users to replace a battery-related support service fees of up to 100 U.S. dollars, while Apple has not been previously informed of this situation to the user. This time, Apple is clearly Chinese companies to learn, in the iPhone mobile phone users in China before the sale officially inform the user on the iPhone mobile phone battery replacement costs.

Method to extend notebook battery life

Posted by batterylhj on Thursday, October 08, 2009 2:15:12 AM

Any person who with the books probably have experienced the embarrassment of the power to find that, in fact, develop some good habits can be very effective books to extend battery life.

* Defragment the hard disk from time to time: hard work, the more smoothly, it also consumes less power. Regular clean-up disk fragmentation can easily do this. Of course, if you are using MacOSX, or Linux, then you can ignore this department, because they are on disk management and use of more scientific than Windows, very little debris.

* Dims your display: the vast majority were in support of laptop display brightness adjustment, and some models even adjust CPU frequency and cooling support systems. You can adjust them to the lowest level of tolerance, which is of great benefit to energy saving. (In WinXP, you can by default AC and battery of different configurations,such as IBM ThinkPad T30 battery .so that books in the plug-in automatically switched through the Vista Mobility Center, it can set up multiple sets of books using the program to fully define the power use)

* Reduce background running programs: iTunes, desktop search, etc., these will increase the CPU load, reducing battery life. When you use the battery when turned off as much as possible all unnecessary programs.

* Unplug external devices: USB devices (including mouse), and WiFi will reduce battery life. When you do not have them when they unplug or turn off.

* Add more memory: More memory allows the use of physical memory to run programs, rather than using virtual memory. Virtual memory is stored in the hard disk, and both slow and expensive electricity. Of course, important to note that, plus the memory also will increase the power consumption, so you must first try to estimate roughly how much your memory, in principle, as much as possible not to use or less use of virtual memory.

* Use the hard disk, rather than use the DVD / CD: hard drives are a lot of power, but the CD / DVD drive is more costly electricity. However, when not in use, they spend almost no power. Therefore, when using the battery, or less, insofar as possible with the use of CD-ROM drive it, put the data on the disc made of mirror and use the virtual drive software to use, that is convenient and energy saving.

* Keep the battery interface clean: It is recommended monthly alcohol clean look at the battery interface. A clean interface is conducive to more efficient transmission of electricity.

* Take good care of the battery such as Dell INSPIRON 8500M SERIES Battery : Do not use the battery a long time. Do not be a good charge of battery power instead of using a long set aside. Once charged the battery power, you use the battery at least once a couple of weeks. Of course, do not use lithium batteries power the whole clean. (Fully discharge only applies to a memory effect of batteries)

* Sleep rather than sleep (hang): Although the laptop can be installed in power-saving sleep mode, and can quickly return to work when needed, but it is not as power-saving sleep. The computer sleep, it can save the current state and, more importantly, it completely cut off the power.

* Reduce the ambient temperature: a computer in a cool environment work will be more efficient. In addition to reducing the ambient temperature, for the health of your computer to do is also very effective.

* Set up and optimize your power options: In Windows, power management panel (Vista mobile center), you can set up and optimize the power options in detail.

* Do not multi-task: When you use the battery,the focus on doing one thing. Do not deal with statements, but also drove Email client, listening to MP3, try to focus to do one thing. If you do not do so, you will be any one thing before you finish all of the electric light.

* To your PC reducing the burden: the higher your books require it, the more electricity charges. The work of sending and receiving text messages or play games or watching DVD than a lot of power. If you're around on the battery,such as TOSHIBA Satellite A70 Battery . then together, like a good thing which is more important to some.

* Taiwan to buy more efficient computer: today's computers has become increasingly efficient, and some manufacturers even introduced their all-weather products. Buy a new computer instead of your old machine that old bar.

* To avoid memory effect: If you are using a older computer, you need to look at the memory effect problem. At least two to three weeks to fully charge and discharge your battery once. Of course, if you are using a lithium battery, you will not be subject to memory effect of harassment

laptop batteries

Posted by batterylhj on Friday, September 11, 2009 1:41:40 AM
Notebook computer battery is its flexibility and stability of the fundamental, mainstream notebook computer standard rechargeable battery system. Rechargeable battery system, including rechargeable batteries and power management systems. The laptop battery is also embodied an important part of portability.

Batteries used in notebook computers are three main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd Ni-Cd, Ni-MH Ni-MH, lithium Li.such as FUJITSU Fpcbp80 Battery

The earliest use of notebook computers are Ni-Cd nickel-cadmium batteries, as battery technology was not advanced enough, so nickel-cadmium batteries have a lot of headaches, drawbacks such as: bulky, heavy weight, capacity, small, short life, there are memories of effect and so on. Therefore, the current nickel-cadmium batteries have basically been eliminated, the following detailed description is no longer it.

Then began to use nickel-metal hydride notebook (NlMH) batteries, this battery has a good price and large power, the same time, "Ni-MH battery is one of the most environmentally friendly battery, pay attention to environmental protection, countries have strongly advocated the use of nickel-metal hydride batteries, because the ease of recycling, and the damage to the environment are minimal. However, nickel-metal hydride batteries and lithium compared, there are still some disadvantages. charge a long time and a heavier weight capacity than a small lithium battery, the battery continued to discharge time too short, there is memory effect, and its memory, while not as big as nickel-cadmium batteries, but still need to discharge, the user must be exhausted before charging.

Ni-MH battery soon be lithium-ion (Li-ion) battery such as HP Pavilion n5170 Battery replacement. Lithium-Ion battery will have a long time ago, and began its use is not safe, we often see charging when burning, bursting, perhaps because of the sake of lithium element too active. Then there is an improved lithium-ion batteries, lithium can inhibit the added element of active ingredients, so that lithium really a safe, efficient, convenient, while the older Lithium-Ion battery also will be eliminated. They are also very simple distinction, from the battery label will be able to identify, lithium battery for Li, lithium-ion battery for Li-ion. Now, laptops to use the so-called lithium, in fact, lithium-ion battery. Lithium-ion battery energy storage density, may at any time charge and continued to discharge a long time, generally about 3 hours. The size of the battery capacity of the main from the marked mAh (milliamp hours) to determine the value, such as the 3000mAh, 4000mAh and so on, value the greater the greater the capacity of the battery.

Of course, there are defects in lithium-ion batteries, such as charge and discharge times of high prices and less and so on. Lithium battery charging and discharging of the number of only 400-600 times, specially modified products, but many times 800. Charge once per day basis, the best lithium batteries, but more than two years. And nickel-metal hydride rechargeable batteries for more than 700 times to achieve certain quality and a good product charge and discharge up to 1,200 times, so that a comparison, the nickel-metal hydride battery live longer than the lithium batteries such as Dell Inspiron 500m battery and nickel-metal hydride batteries than the price of lithium batteries much lower. View of this, there is no perfect laptop batteries.

Common brands of laptop batteries the vast majority of the square. On the market also has a small number of ultra-thin notebook using cylindrical batteries, such as the SONY 505 series, Toshiba PROTEGE series. The weight of the battery varies according to the material and models, such as the size and shape of the same nickel-metal hydride and lithium electricity, the weight is far too small.

Volume size, mainly from the marked mAh battery to determine its Chinese name is mAh. MA hours the size of the notebook directly related to the use of time, but it can not be generalized. Battery life notebook configurations with a great relationship, for example Well, the HP 6100 notebook with a PIII-M, MOBILITY RADEON graphics cards and many other energy-saving technologies in hardware, with the 4000mAh battery, use of time up to 4 hours above. Using the Toshiba 1800 desktop CPU, although equipped with a 4500mAh battery, use of time can only reach 3 hours. Able to meet the needs of the general going out to work. This also indicates that the notebook battery mAh not only related to hardware, energy-saving technologies is very important.
