Why Li-polymer into the mainstream of EVO N410C battery
Sony battery incident can be said that the current in the industry, one of the most talked about topics so far Apple, Dell, Fujitsu, Hitachi, IBM / Lenovo, Panasonic, Sharp, Toshiba, Gigabyte and Sony have developed their own battery recall activities related to the number of recovered cells close to the 10 million mark. For a time, the crisis caused by lithium batteries for SONY bear huge losses, but also become erase painful memories. Traditional lithium batteries has become a huge security risk lay in the minds of businesses and consumers a knife.
Traditional liquid lithium-ion batteries as an efficient energy carrier has been widely used in communications, electronics industry, especially the mobile phone, PDA and other personal communication tools. According to statistics, the global demand for lithium-ion battery has reached 1.3 billion, and with the continuous expansion of application fields, the data in every year. For this reason, with the lithium-ion inspiron 5150 battery in various industries the rapid surge in usage, the battery safety performance is increasingly prominent, not only requires lithium-ion battery with excellent charge and discharge performance, but also requires a higher safety performance.
Novel Polymer Lithium-Ion battery wind and water
In recent years, with the rapid development of communication technology, mobile phone color screen technology, multimedia technology, Bluetooth technology and camera technologies continued emergence of the battery capacity, size, weight and electrochemical performance indicators such as a higher demand, Traditional lithium has become increasingly unable to meet the new requirements. New type of polymer lithium-ion Inspiron E1705 battery appears to meet this demand. Polymer Lithium-Ion battery is the original steel, aluminum battery developed on the basis of the third-generation lithium-ion battery, with its lighter, thinner, higher energy density characteristics, by domestic and international communications terminal manufacturers and design companies in favor of . It not only has a lithium-ion battery all the technological advantages, but also has a higher energy and better safety performance.
In order to confirm the safety performance of lithium polymer than conventional lithium-ion Travelmate 240 battery later, the group has conducted some careful experiments and testing. The batteries have have a UL, CE and other international certification, with high quality and safe and reliable guarantee. Of polymer lithium-ion water, after the success of the initial trial, now it has been widely used in various well-known global companies such as Ipod, Samsung, LG, MOTO, etc. a variety of mobile digital products.
It is reported that polymer lithium batteries used in addition to the above-mentioned mature digital device, also some new high-tech products in a small test to merit, and begun to taste the victories. Not long ago, a new type of mobile power, they made full use of lithium polymer light Toshiba PA3451U-1BRS, thin, and the characteristics of high energy density achieved without connecting the power, we can mobile phones, digital cameras, handheld computers, game consoles, MP3 , MP4, Bluetooth headset for charging function, greatly solved the problem of power shortage mobile digital products. At present, this called "too much industry, mobile power" of the new products from the domestic well-known enterprises Digital comprehensive sales agent.
Multiple advantages of Li-polymer escort
Any with "electricity"-related products, bear the brunt of security issues. As the polymer lithium Tecra M3 battery on the use of plastic flexible packaging in the structure is different from traditional liquid metal batteries in case of potential safety problems, the traditional liquid batteries are explosive, while the gas-polymer batteries a maximum of only drums, will not be produce any harmful personal and property safety. In addition, the polymer lithium battery installed on the engineering model for automatic protection board, can short circuit, over charge, over discharge for effective protection, without fear of overcharge or charge does not eat into the atmosphere. This provides batteries using this product provides adequate security, safety features far superior to the traditional liquid lithium-ion batteries.
Speaking of digital products, "light", "thin", etc., is very difficult to get around the target in the past. The weight of the battery of digital products directly affect the overall quality, due to polymer Thinkpad R50 battery lighter in weight than steel of equal-capacity lithium-standard 40 percent lighter than aluminum but also 20% lighter and the battery, so the use of its digital product weight is greatly reduced. In addition, polymer batteries, the thickness of 1mm can be achieved below will not affect the thin level of digital products. At the same time, polymer battery sizes of steel compared with the same battery capacity by 10 ~ 15% higher than the aluminum battery 5 ~ 10%. The above-mentioned mobile power industry, too, due to the exclusive use of lithium polymer batteries, the fuselage is only 100mm × 55mm × 17mm, to achieve a small, stylish, light, which greatly satisfy the needs of carrying out. Compared with similar products, and too mobile power to achieve the energy industry, the volume ratio of the maximum.
It is worth mentioning that, due to polymer Lenovo 40Y6799 batteries used in the material itself has sufficient security, so the battery protection circuit design, eliminating the need for PTC and fuse, thereby saving the cost of the battery. In addition, the internal resistance of polymer batteries than ordinary liquid batteries is small, greatly reducing the battery's self-consumption, to a certain extent, to extend the standby time of digital products. The above-mentioned mobile power, for example, one filled with too much power industry, power supply, power consumption is equivalent to ordinary mobile phone batteries or digital camera 4 ~ 7 times, which means that you can use to recharge mobile phones or digital cameras for more than 4 ~ 7 times . For ordinary MP3, Bluetooth headsets, CD players, video machines and so on, so the industry can charge power supply 10 to 15 times more;
In addition, the poly-lithium batteries can be designed into any shape, but also according to customer's needs increase or decrease the thickness of batteries, and some even based on mobile phones, digital cameras and other shapes tailored to take full advantage of the battery shell space, to enhance battery capacity. It also has no leakage, no heavy metals, pollution and other environmental features. Right now, the use of polymer batteries, and the Pavilion ZD7000 battery products are rapidly increasing popularity quietly become an essential ideal mobile life.
Polymer lithium battery into the mainstream is imperative
Polymer lithium batteries in safety, size, weight, capacity, discharge performance than the traditional liquid lithium batteries is more advantage. In the past, domestic and international polymer lithium-ion Dell laptop battery manufacturers to use more U.S. production of Bell Labs, Bellcore process. However, because this method processes cumbersome, inefficient, equipment and production costs of large investment and higher shortcomings, serious constraints in polymer lithium-ion battery development and industrialization.
In recent years, a large number of laboratory work, based on a number of key materials through an integrated technology, the success of some enterprises in China have developed a polymer lithium-ion battery. According to industry data shows that until last year, polymer lithium IBM laptop battery has been dominating the world mobile phone battery market, about 1 / 4.
Polymer lithium-ion battery is recognized as the most development potential and future applications market batteries. It is predicted that in the next few years, will replace the liquid lithium-ion battery for nearly 50% market share, has a broad development prospects, are Japan, China and many other major battery makers focus on investment and research and development directions. Can be predicted that around 2010, polymer lithium-ion Sony laptop battery is the preferred next-generation mobile digital devices, will also become the most promising alternative to mass lithium battery products.
United States commitment to the battery industry since 2011, is not to add mercury button batteries
U.S. Electrical Manufacturers Association (NEMA) has announced an industry initiative: from 2011 onwards are not button Toshiba laptop battery (the battery is widely used in watches, calculators and hearing aids) to add mercury. Button batteries are the only batteries still contain mercury added.
The traditional use of mercury in batteries by adding the method to reduce leakage and storage will lead to the battery to shorten the battery life of the internal gas formation. In view of increasing concern about the environment, the battery industry to develop alternative products, and in 1993 phased out years ago, in ordinary-size alkaline batteries and zinc carbon batteries to add mercury. However, due to technical limitations, some of which is due to the size of a small button Apple laptop battery, button batteries hindered the removal of mercury.
Nevertheless, the battery industry is making efforts to reduce the annual consumption of more than 1,000 tons of mercury. From 1991 to 1995, batteries for hearing aids in sectoral phase-out of mercury oxide batteries, the battery in 1996 was "mercury and rechargeable battery management regulations" prohibited. Made entirely in the recent removal of mercury-added button cell before the decision, the HP laptop battery industry has put the amount of mercury button batteries down to a record low value - less than the federal limits prescribed 25mg half.
Of mercury in lakes and streams in the accumulation, and further led to the production of methylmercury. Methylmercury in fish, people, animals, accumulating up to endanger life and health level. American National Standards Institute (ANSI) pointed out that methylmercury can lead to fertility decline, affecting development and behavior and even death, depending on the size of the exposure.
As a participant in this initiative, participating organizations and institutions will invest all the resources dedicated to resolving problems arising in PCGA-BP2EA battery production, and constantly improve the technology level.
