In the U.S., rechargeable Digital Camera Battery market in 2005 from 2001 to 25 billion dollars to 42 billion U.S. dollars.
Freedonia analyst KenLong said the growth in demand for rechargeable batteries is that notebook computers, handheld computers and mobile phones such as the popularity of portable electronic equipment. He pointed out that the use of digital cameras and multi-function handheld Canon Battery computers 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 special space.
Long pointed out that in 2001, 34% of rechargeable batteries are lithium-ion Canon BP-208, Canon BP-511 battery. In 2005, this figure will increase to 45%. Lithium-polymer 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, 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 Canon LP-E5, Canon NB-1LH 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 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.

Reporter yesterday visited the market, found that after the Spring Festival, the local market price of electric bicycle battery is up 10% to 15%. The distributor has also received notification of manufacturer: electric vehicle batteries will be an increase recently.
The most commonly used lead-acid electric vehicle batteries as the main raw materials of lead, Canon NB-5H, Canon NB-5L lead prices rose along with it. Evening News Changliang map
People: a kind of battery in a day, up too far too soon to
"A few days ago, my electric vehicle batteries stolen, and 14 to maritime East wholesale markets to buy electric cars, but no too expensive to buy, would like to find a cheap, did not think up the next day, and each Block rose more than 6 batteries. on the third day to go, each block of the battery has gone up Canon NB-6L more than 10 pieces Casio Battery. "Members of the public, Mr. Shin said that the battery is also up too fast, and price increases the frequency people unbearable.
Dealer: Spring Festival has been up after the recent would rise about
Yesterday morning, sailing East electric vehicles wholesale distributor Ms. Qin said, after the Spring Festival, the electric car battery prices have been rising, the wholesale price of each cell transferred from the more than 130 yuan on a 150 yuan, or 10% to 15%, manufacturers has informed the near future will be an increase.
It is understood that production of electric vehicle battery lead is the main raw material, accounting for up to 70% or so. Lead in price from more than 10,000 yuan per ton last year, increased to 17,000 yuan per tonne now. An electric car manufacturers say that, in 2006, the Casio NP-100, Casio NP-20 battery prices have raised three times, and now lead prices, the battery price increases are taken for granted.
Ms. Qin way to predict future price movements, the battery: "Battery prices will definitely not down to the end of this year, the battery prices will rise even higher. By then, electric cars will reach a higher price."
Distribution of electric vehicle parts, said Mr. Ban, who so far have not prices, but the manufacturer has received notice of the battery price will be adjusted in the near future.

An electric car sales, said the owner of Miss Song, but does not rule out the battery prices have gone up with the speed too fast, resulting in electric car prices . "Currently, many electric cars dealers are in the wait stage, to see the market trend."
The road to fuel cells? Experts feel the pulse of your direction! Casio NP-30, Casio NP-40, Casio NP-L7
Taiwan's ITRI IEK for direct methanol fuel cell (DirectMethanolFuelCell, DMFC) research report published by Market, although the direct methanol fuel cell with high energy density, the future potential applications well received by good, but at this stage still can not replace lithium batteries In the application of 4C products, mainly in its high price difficult to reconcile with the current widely used secondary battery match.
IEK industry analysts are like Jin said, the semiconductor industry Moore's Law (Moore'sLaw) to say that every 1.5 to 2 years will increase the effectiveness of a semiconductor-fold, while the increase in recent years, battery technology is only about 9% per year is expected mobile phone and other portable The power consumption of electronic products will be substantially leap forward, while the lithium-ion battery performance of simultaneous breakthroughs in the theory has its limits, making electronic products will have a large energy gaps between supply and demand; and direct methanol fuel cell can exceed the energy density of 1,000 Wh / kg , in order to bring about the future high-performance portable DSLR Battery Grip power solutions.
Portable fuel cell system at this stage in order to DMFC technology-based applied to 4C products to Japan, Korea and electronics industry's most active, while the U.S. portable fuel cell maker is more of a military use for the initial applications. Just like Jin said, DMFC systems can be divided into four parts, one for the fuel cell body (from a few pieces FuelCell stack into the Stack), the other for the peripheral devices (components of main components are: responsible for transport of methanol fuel Pump, and the control of oxygen, CO2, heat and out of the Fan, Blower, and monitoring of methanol concentration sensors ... and so the fuel supply and water and thermal management components). Third, the power control system (including power conversion, energy management control, humidity control, load control components, etc.), four fuel supply system (mainly constitute the components of a mixture of methanol fuel tanks and pure water tanks).
Present DMFC system costs, Stack ontology approximately 7 ~ 80%, one of the most Canon BG-E2N Battery Grip crucial parts of MEA (including the gas diffusion layer GDL, Membrane, Electrodes), cost accounting for about Stack cost 1 / 2, while the MEA cost of about Qi Cheng is a layer of precious metal from the electrode catalyst material. Just like Jin said that as a direct methanol fuel cell system involves many materials and the operation of peripheral components and related industries on the downstream from the fuel supply to the system application, covering many areas.
Just like Jin also pointed out that in the 4C with the commercialization of DMFC product has not yet before the cell stack or battery (Stack) of the upstream materials and key components of the market pioneer, because of its direct methanol fuel cell's fuel efficiency and energy density there are a big impact, so the entire fuel cell industry occupies a pivotal position, the main profit source for the current industry.
In order to function as if the fuel cell system CPU of the MEA, its product gross margin in excess of 50%, so it attracted many European and North American manufacturer of professional materials into this area; but because of the size of the downstream application market is still small, the M & A activity among manufacturers in recent years, are also common. As the market barriers to entry are relatively high, at this stage the upper reaches of the key fuel cell materials and components controlled by a small number of large international companies, such as JohnsonMatthy, Dupont, Toray other hand, it belongs to oligopoly market structure. If these alone Nafionembrane markets, Dupont are entitled to high monopoly profits.
Just like Jin said that although the fuel cell industry is currently present oligopoly situation Canon BG-E3 Battery Grip, Canon BG-E5 Battery Grip in the upper reaches of the supply chain, but not in price competition among firms as a means, but through innovative R & D to make its own product technology upgrade to meet the changing portable consumer electronics product demand.
Although the direct methanol fuel cell with high energy density, but at this stage still can not replace lithium batteries in the application of 4C products, mainly because of the acquisition cost of the fuel cell except expensive, consumers can not easily give up almost for free while charging the secondary battery to spend money to purchase additional boxes unfavorable factors such as fuel, the fuel cell can not be an immediate increase in Feed-in the amount of fuel to match the changes in peak load demand for electricity is also a problem.
In addition, at low temperature (0 ℃ below) can not start the fuel cell environment, we must help the battery as the main power supply. Therefore, 4C into the early commercialization of fuel-cell stage, will be paired together with the lithium battery hybrid system (HybridSystem), by a lithium battery peak electricity demand, while other fuel cells, a continuous supply of electricity; or when the power outlet can not be used, the fuel cell can serve as ACAdaptor or battery charger function.
Just like Jin stated that at the beginning stage, fuel cells and lithium batteries will be complementary goods, rather than a substitute product. The future, until fuel cell technology is more mature, simple fuel cell system can be integrated in 4C-product, and in full by 4C system power supply. Is expected in 2010, Canon BG-E6 Battery Grip, Canon EOS 20D Battery Grip, the fuel cell alone power supply the products 4C can there be a significant development.

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."
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.

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."
