Laptop batteryequipment, and promoted the rechargeable laptop battery market and the battery industry. Portable equipment to increase run-time, mobile phone call requests for extension of time, which requires to increase the energy density of chemical batteries. Be able to meet these technical requirements are lithium ion and lithium polymer batteries. Sony's first production in 1990, a rechargeable lithium-ion , lithium-ion sony battery has been used in notebook computers and mobile phones, the future may also be used in digital telephone. Lithium polymer batteries are also a new generation of batteries, large quantities in 1999 to enter the market. In addition to lithium polymer batteries are solid polymer electrolyte instead of liquid electrolyte, the other with the lithium-ion is basically the same. Polymer electrolyte material is formed by the PA3331U-1BRS melting of the general body film, the main body in the dissolved polymer such as polyethylene oxide as a solvent for non-mobile. The benefits of lithium polymer batteries are made of any shape and can be relatively light, this is because it does not contain heavy metals and do not have to maintain electrolyte leakage of the plastic case. They have better performance, the ideal state lithium polymer capacity of thousands of mA / h, and more security. Solid-state electrolyte such as a sealed gel, in charge of natural process will not easily disintegrated. Lithium polymer batteries and lithium-ion dell battery technology can replace the battery NiGd. But the price is too high, the market has not fully accepted, especially lithium polymer technology. Darnell Group analysts think Brush: polymer batteries will not be expensive than the lithium-ion , the current production is indeed a lot of expensive, which promoted the lithium-ion battery technology. Previously for the lithium-ion laptop batteries are the cost of 41.42 U.S. dollars, the polymer used in laptop batteries are the cost of 60.80 U.S. dollars. Anyone who does not believe that lithium-ion batteries are cheaper than the polymer one of the advantages of batteries. Some PA3098U-1BRS manufacturers are turning to the lithium polymer battery technology, Toshiba America Electronic Components Inc. (TAEC) has invested heavily in this area. Lithium polymer lithium-ion are shifted because of the Japanese market needs and lithium-ion has become very cheap. Price change and increase productivity and earnings are not necessarily the same. TAEC think, lithium polymer batteries are tight, and it is the possession of the goal 3 ~ 6mm thick battery market. Will enhance production capacity, from the current 1.5 million to improve in 2001 to 1,000,000 2. And as new technologies are developed, prices will fall. Some people in the trade that in 5 years, lithium-ion batteries and lithium polymer batteries will be a small price gap. Face the future application of the market, many people naturally from small portable devices and mobile phones turned to other areas of application of the PA3084U-1BRS . The largest market is the automotive application.
At this stage, the Apple battery industry who are optimistic about the enormous profits of the automobile market, the implementation of stringent environmental protection measures and feasible energy requirements and the electronic hybrid vehicles are not development, lithium polymer have a wide application prospect. A referred to as the "T" and with 14-inch screen and remote control of the processor to connect to another belt and wrist at the computer, the mobile hospital system and comply with the Wireless Application Protocol phone can be on the Internet (figure and there is sound) All these applications are required to charge and store energy, and the smallest space. Prediction Polymer is expected to this year's shipment volume reached 19 million, 1.4 million last year. Conservative freight is expected to 3.25 million per month in the first quarter of 2001 shipment volume of production capacity is 2 times. Analysts think: to other products based on lithium polymer in the battery of the total share of income will increase, for instance, Brush said: PA3399U-1BRS because sales fell, lithium polymer batteries to 2003 or 2004 market share NiCd batteries will be over. Rechargeable IBM battery market from last year's approximately 4.4 billion U.S. dollars in 2004 rose to 5.8 billion U.S. dollars, the total annual revenue growth rate of 5.5%. According to Kline & Company in "the world's advanced battery technology opportunities from 1997 to 2007" report, its conclusions more specific, and is projected to 2007, the annual market demand for lithium polymer batteries for at least one billion U.S. dollars. 50% of these demands from the United States and Western Europe. No matter how the actual production, the application in the mobile phone lithium polymer batteries IBM ThinkPad T40 ,IBM ThinkPad X60 ,IBM ThinkPad R60 ,IBM ThinkPad R40 are the biggest growth. Light and easy to use PA3395U-1BRS than its more popular and more competitive, with the development and application of new technologies, the price will eventually come down. Product Development Matsushita Battery Industrial Company in May 2001 at the beginning of mass production of large-capacity lithium polymer battery, a capacity of 1650mA / h, the negative terminal of the are manufactured using new materials. Toshiba's OEM battery group also issued a personal digital assistant for the 2.5mm-thick series of lithium polymer batteries, the company said: The use of the structure of products using a new cathode material and the structure and capacity of the existing capacity of 1.7 ~ 3.3 times (now the largest capacity of 1000mA / h), mass-produced products, in May 2001 before the 500,000 per month to the end of next year one million per month 1. TAEC is to provide a new design over the existing design of the advanced lithium polymer, in particular, are suitable for operating temperature range. Electrochem capacity has developed at 35 ~ 6500mA / h, thickness 0.65 ~ 6.3mm at a variety of PA3250U-1BRS capacity. PolySter company plans to launch at this time of 1200mA / h battery, specifications for the 46? 50? 6mm, used in BP and personal digital devices, the capacity of 1000mA / h battery for mobile phone; 850mA / h battery for the Web -access, 310Ma / h batteries for wrist instruments; 160mA / h (30? 29? 3.2mm) for earphone. Ultralife Batteries Inc. has recently announced the completion of a production line, the production of thick 0.5mm, thickness 4.4mm after packaging capacity of 700mA / h, the weight of about 20g of the battery. Other lithium-polymer battery technology is in various stages of development or near the production stage, such as Lithium Technologies, Inc., aim for the automotive market are the 9A / h, the specifications for the 4? 8? 0.25 inches of the battery.

Nokia Corp. is offering to replace 46 million PCGA-BP71 made by another company for use in its mobile phones because of a risk of overheating, Nokia said on Tuesday.
The faulty batteries were manufactured by Japan's Matsushita Battery Industrial Co. Ltd. and sold in a wide range of Nokia phones, from its low-end 1100 family of products to its pricier N91 and E60 devices.
The overheating can cause the sony laptop battery to "pop out" of the phone while it's being recharged, said Nokia spokeswoman Marianne Holmlund. She said there was no risk of fire, although it was unclear what caused the minor incidents reported.
"It may be that the device left a small burn on a shelf while it was recharging, it's hard to VGP-BPL2 say for sure," said John Devlin, research director for mobile technologies with IMS Research in the U.K.
People concerned about the problem can get their battery replaced for free, Nokia said. It set up a Web page that lists the phone models and describes how customers can check if their battery is affected.
The problem exists only with Matsushita sony vgp-bps5 manufactured between December 2005 and November 2006, and the phones would have been sold worldwide during roughly the same period, Holmlund said.
Nokia reported selling 347 million phones in 2006, making 46 million a significant proportion of its annual sales. "It is about 10 percent of all the phones sold, but we are talking about 100 incidents, which is only a tiny proportion," Holmlund said.
Nokia expects Matsushita to bear "certain financial responsibilities" for the replacement VGP-BPS3 program, she said. Peter Weber, a spokesman for Matsushita in Europe, said the financial terms are being negotiated now between the companies.
It's the first time Nokia has had to offer such a replacement program, Holmlund said.
Such problems in phones normally arise because of counterfeit batteries, making this case "a little unusual," Devlin said.
The problem is unlikely to affect other makes of cell phone since the batteries were VGP-BPS5 designed especially for Nokia, Weber of Matsishita said. Cell phone batteries are typically designed and manufactured for a particular phone maker, Holmlund confirmed.
It's only the latest incident involving rechargeable Lithium ion batteries used in portable electronics products. Late last year laptop makers including Sony Corp., Toshiba Corp. and Dell Inc. offered to replace a total of 8 million laptop batteries because of a manufacturing defect in Sony-made batteries that left them vulnerable to short-circuiting and catching fire.
Nokia said it will work with Matsushita and the Sony Laptop Battery "relevant authorities" to investigate the problem.
