To stimulate growth in sales of PDA cell phones will reach 16.2 billion U.S. dollars
According to market research firm laptop battery Freedonia Group, said, cell phones, PDAs and emerging wireless devices in the next five years will be to promote the growth of rechargeable battery market. The world of non-rechargeable lead-acid batteries sold in 2006 from 2001 to 101 billion dollars to 162 billion U.S. dollars. In the U.S., rechargeable battery market in 2005 from 2001 to 25 billion dollars to 42 billion U.S. dollars.
Freedonia analyst Ken Long said the growing demand for rechargeable batteries is that notebook computers, handheld computers and mobile phones such as the popularity of portable electronic equipment. He said that the use of digital cameras and multi-function handheld computers sony battery and other power-electronic products will increase battery. Most of these applications use lithium-ion batteries.
Long said the lithium-ion batteries will be the product of choice in many applications because such products can provide a longer working hours. However, lithium-polymer battery will also get some market share because the battery is flexible, portable devices can be made a vgp-bps2a special space.
Long said that in 2001, 34% of rechargeable batteries are lithium-ion battery. In 2005, this figure will increase to 45%. Lithium-polymer vgp-bps2b battery market share from 2000 to about 2% to 10%.
Used in electric tools, and some low-end portable electronic devices nickel-cadmium batteries will lose market share. In 2000, nickel-cadmium batteries can be Chong Chongdian battery market accounted for 35% of the market. By 2005, nickel-cadmium battery market share will drop to 16%. For low-end mobile phones and handheld game consoles nickel-metal hydride batteries will maintain 15% market share.
On the Sanyo, Panasonic, Toshiba, and Rayovac batteries and other manufacturers vgp-bps2c, the main challenge is the production of smaller batteries and increase battery life. Another problem is to reduce the battery charging time.
Earlier this year, Rayovac Corporation announced the I-C3 technology. Just 15 minutes of this technology can be finished for the battery charge power. The technology to put the battery charge function, rather than inside the charger. In this way, the vgp-bpl2c battery charging time is not only short and full power. This battery can be charged 1,000 times. However, the price of the battery than the battery does not use this technique more expensive.
Jinweizhou DC system battery power plant renovation project completed
Recently, five-ling's Island power plant near the end of the transformation of DC system battery was successfully completed.
Island power plant near the end of the original battery DC system put into operation due to a longer vgp-bps8 time, there is some aging of battery rupture, decreased charge capacity issues such as a serious threat to the safety of the whole factory and stable operation of power generation equipment. After transformation, using well-known manufacturers battery capacity of 400Ah lead-zinc-life maintenance-free batteries, 350Ah battery than the original use of time is more durable, thus greatly improving the DC system Jinweizhou power plant to run security and stability. After you install a new battery, has carried out 10%, 100% charge-discharge tests, the measurement data of qualified, batteries and stable operation.

Charge is only five minutes promising solar cell phone vgp-bpl8, batteries
What consumers are most concerned about the phone function? China's largest chain of mobile professionals Dixon, vice president of Jin Xin Tong said: Consumers are no longer the pursuit of "high, new, strange", but rather a more pragmatic, what does not require any, can a rational thought. At present, consumers have to see a major screen appearance, audio-visual experience and other factors. These features are now popular, the most promising solar cell first, second, digital TV. Solar cells on behalf of phone has a battery life that allows mobile phone charging in the sun, both fashionable and environmentally friendly. Digital TV is a 3G mobile phone users in a basic needs.
According to experts, the key bottlenecks in the current solar cells is the conversion of solar vgp-bps9 energy to electrical energy is not high, it is not practical. But the recent Third China (Shenzhen) International Cultural Industry Fair on display solar energy industry business mobile power to bring an enchanting, winding paths of hope, up nearly 20% of the conversion rate allowed to become the industry's technology leader, the day's turnover of one million mark, which indicates that there is a mobile power solar business people surprise market prospects. SASAC officials Lucci Chun, said that with all the environmental awareness of the general increase in energy-saving awareness, self-drive tourism market continues to expand, like Yang Technology Limited, Shenzhen, introduced high-tech solar energy business will be subject to consumers more mobile power come more and more attention, but also represents a new charger direction of development.
Nowadays mobile phones have become an indispensable and important communication tool, along with increased competition, mobile phone VGP-AC19V13 communication has also been given more significance than, for example, music players, online business, but the arrival of the 2008 Olympic Games, it also would assume the the important task of mobile TV, all for the phone's battery is a great test. So all kinds of spare batteries, universal charger, cell phone, like springing up first emerged as a partner, but they failed to become the market mainstream, because they do not have the energy regeneration function, product quality can not be achieved publicity. While yang energy "Daylight's Box" solar emergence of commercial mobile power has changed this situation. It is up to 20% of the photovoltaic conversion rate can quickly convert the energy of sunlight into electrical energy, and provide to those in need of digital products. As long as the light 5 minutes, so that digital products can be "revived" and efficient conversion rate for "Daylight's Box" has become a truly mobile power uninterrupted. Yang was able to grasp the solar technology that humanity has ignored the source of life, with its ubiquitous radiation has changed the face of the embarrassing situation of conventional energy sources, to digital products has created a new energy era.
Welcome to Wikipedia, there are "tolerance" is great
In fact, the current wide variety of solar products, but generally speaking, is to meet the needs of the majority mobile phones, such as "Sunlight magic" box so you can cover both the mobile phone, MP3, MP4, DV, PDA, etc. 3.6-9.5V digital power products mobile power needs of only a handful, which also fujitsu battery focused on body a "sun's Box" and "new" ideas are people-oriented manufacturers to design the best interpretation.
Yang Xu, chairman of science and technology can be mentioned, said: At present, countries are emphasizing a unified standard mobile phone charger, but Yang could have been far from walking in front of peers, and almost all of the need for recharging electrical appliances market, communications, digital products, as long as a "Daylight's Box" solar commercial mobile power can be resolved.
Japanese researchers developed a new type of lithium battery materials, to prevent overheating and explosion
May 24 news recently, one can prevent battery overheating during use of new materials come out, and the use of this material will be produced on-board lithium batteries safer than ever before.
The new polymeric materials to avoid future recurrence of a similar kind of a result of the lifebook t4010 battery explosion last year, which led to large-scale recall of notebook computer lithium battery incidents. New material can enhance the safety of batteries, lithium batteries are widely used for future hybrid and electric vehicles to clear the road.
As the lithium battery replacement battery products than any other lightweight, so it is used in notebook computers. It can replace the nickel hydrogen storage batteries are used in the field of automotive batteries, so that not only saves space, you can also reduce the weight to improve fuel economy. But so far they have not been widely used in the field of automotive batteries, in which security issues are also partly responsible.
When the battery due to over-charging or internal electrode touching lead to short-circuit could overheat, resulting in the battery explosion fire. While the notebook computer on fire is very dangerous, but the device's battery is generally only a few battery cell. Car batteries contain thousands of cells die, once the consequences will be much more serious fire.
Last year, due to a large number of cells in the production process accidentally left some of the core metal particles, resulting in a large number of Apple and Dell and other notebook computer makers to recall a number of one million notebook computer batteries. In rare cases, these metal particles can penetrate inside the lifebook t4020 battery to prevent the positive and negative electrodes touching the plastic film. This will cause the battery to overheat, resulting in battery failure within the separation layer is further see more short-circuit phenomenon, so that overheating of the situation continued to deteriorate. Reached a certain temperature, the electrode materials will decompose and release oxygen, the speed of batteries overheating will be faster, and eventually led to an explosion and fire.
ExxonMobil Petroleum & Chemical Corporation (Japan), the branch's Tonen Chemical (Tonen Chemical) company researchers have developed a new material of the isolation layer, it can more effectively prevent the battery overheating. United States New Mexico Albuquerque's Sandia National Laboratories (Sandia National Laboratories) advanced technology development project manager Pete Rose said that this new material can slow reaction time, the battery overheated and burst into flame and allow to cool down before. Sandia National Laboratories is currently testing the new isolation layer of security.
Isolation layer is made of electric insulating material, there are some holes on it so that the battery charge and discharge process of lithium-ion battery electrodes to swim between. Isolation layer reaches a certain temperature that is 130 degrees Celsius when you will begin to soften. Above the hole so that it was closed, cutting off the current between the electrodes. Under normal circumstances, this can prevent the battery to overheat. However, if the battery temperature continues to rise, isolation layer material will completely melt fracture which led to a large number of current short-circuit, and then the battery will heat up speed, if the battery temperature over 180 degrees Celsius, the electrode materials will begin to decompose, releasing oxygen, which led to battery electrodes and lifebook t4210 battery explosion fire.
Traditional isolation layer at temperatures over 150 degrees Celsius and then will break down, but the new material before the temperature reaches 190 degrees Celsius can be stable. Ross said the new barrier that can prevent a large number of current short-circuit phenomenon, thereby preventing the battery overheating and accelerating cause the explosion.
The performance of the new barrier is more stable because it added more than one polymer, one polymer at 130 degrees Celsius to soften and cut off the current, while another layer of polymer can guarantee against injury to isolated to prevent short circuit. Tonen's R & D manager Koichi Kono said that because as long as the transformation of existing production equipment can produce the new material, so it will soon be able to begin mass production and the market. He said: "We are ready for commercial production."
Other companies have also been in the development of lithium batteries to ensure a safer alternative materials, including the use of different electrode materials or non-flammable electrolyte, or in cells of the thin layer of ceramic material to ensure no short circuit between electrodes. While the ceramics can withstand high temperatures, but FPCBP155 fujitsu battery whether they can be integrated into the production process, as well as whether the costs of doing so is too expensive and other issues remained unresolved. Ross said: "The purpose is to allow the battery slowly expired without an explosion."
