The lithium polymer battery into the mainstream
When the lithium polymer battery into the mainstream
Polymer lithium-ion battery for its safety, high-capacity, low-profile characteristics, and so on, such as mobile phones are becoming the new choice for digital equipment. Experts believe that the next two to three years, the polymer lithium dell 6y270 battery, dell c1295 battery, dell inspiron 500m battery, dell inspiron 510m battery market will account for 20% -25% of the share.
New choice for 3G mobile phone batteries
As the 3G era, mobile phone battery will be the key to the development of constraint factors. Battery Co., Ltd. Tianjin power of God was once president of Qin mobile phone package at the meeting in Tianjin, pointed out that if the battery technology can not maintain the volume unchanged weight of a substantial increase in energy storage, batteries will ultimately affect the mobile communications industry. God is the power of ordinary liquid lithium-ion batteries, one of the major manufacturers, Qin pointed out that if raw materials on the battery there are no major breakthroughs continue to enhance the capacity of lithium batteries is extremely difficult; and in the capacity of the existing critical state conditions, you must give a lower safety factor.
Liquid in the traditional lithium-ion batteries based on the development of lithium-polymer battery (hereinafter referred to as lithium-poly battery), just to make up for the performance deficiencies of the traditional Li-ion battery. First of all, as a result of the use of plastic flexible packaging composite film, as opposed to the use of aluminum shell, such as traditional hard-packed lithium batteries, the explosion is not easy, with higher security. Secondly, lithium poly batteries lighter, thinner, larger capacity. According to Chief Engineer of TCL Golden Energy Limited Guo Chuntai introduced, TCL by the end of this year will be introduced to the energy density of 500 Wh / l lithium poly batteries, will be the current world's highest energy density. According to New Energy Technology Co., Ltd., Dongguan (hereinafter referred to as ATL), introduced Mr. Zhou Marketing Department, ATL poly thinnest lithium battery can be 0.5 mm, which is the traditional lithium-ion battery is inconceivable. Third, in principle, lithium batteries can be designed together into any shape, for cell phones and other mobile devices designed to provide a very good condition. Fourth, as a result of the use of polyethylene gel electrolyte lithium batteries, or solid substances, will not leak, thus reducing the pollution.
TCL Guo Chuntai told reporters, after nearly a decade of development, the performance of lithium batteries together a great improvement, for example, lithium poly batteries before the existence of low-temperature charge-discharge performance under the conditions of the problem of the poor, have been resolved. Materials Chemistry in the present has been the premise of new breakthroughs, poly lithium-ion battery energy density, weight indicators, such as volume ratio leading to ordinary lithium batteries, security, better performance. He said: "To be sure that the lithium-poly battery will be important to the choice of 3G handsets."
Poly and Li-ion battery as a domestic supplier of the other mainstream ATL, are also very optimistic about the 3G mobile phone battery applications. Mr. Zhou its marketing optimistic that the lithium-poly battery will become the mainstream 3G mobile phone batteries to choose. At present, the design of 3G mobile phone Li-Poly dell inspiron 600m battery, dell latitude d500 battery, dell latitude d505 battery, dell latitude d510 battery manufacturers show great interest in the 3G mobile phone used in this new technology. It is understood that there are a few domestic manufacturers of 3G handsets in the small-scale trial of poly lithium battery TCL.
The next to occupy the market share of 20%
In addition to applications in mobile phones, poly lithium batteries can also be widely used in a variety of mobile digital devices. It is understood that the present poly most widely used lithium batteries in the field of small electrical appliances, such as Bluetooth, MP3 and other products for more than 90% of lithium batteries used together.
According to Guo Chuntai , the first two years people have forecast Lithium Poly battery this year and next year will occupy 30% of the lithium battery market, but the reality is that the current lithium batteries together occupy only 12% -13% of the share. According to his analysis, resulting in the gap is due mainly to the following points: First of all, 85 percent of the lithium battery of application market mainly concentrated in areas such as notebooks and mobile phones, 15% applied to other mobile digital devices. Notebook batteries and lithium batteries to occupy the entire half of the market, but also one of the fastest rising market, basically used in an ordinary liquid lithium batteries, the lithium battery to the poly is not a lot of space left. Secondly, the design of mobile phone batteries are built-in and standardization trend of cell size and shape requirements of a wide range of less and less difficult to Poly Li-ion battery performance and the price of ordinary lithium batteries resulted in a strong impact. Third, 3G mobile phone market to start a large-scale . Based on this, Guo Chuntai that: "the next three years, Li-Poly battery can hold 20% -25% of the lithium battery market is a good achievement."
ATL believes that Mr. Zhou, Li-Poly battery due to the security of having a natural advantage, it will be within a certain period of time gradually replace the traditional lithium-ion battery. However, compared to traditional lithium-ion battery, the acceptance of new things and the process takes time.
Domestic suppliers to catch up
Li-Poly batteries in the industry, at present has about 10 competitive manufacturers. Major foreign manufacturers Sony, Samsung, LG and so on, mainly domestic TCL, ATL. It is reported that Li-Poly batteries in the market, Sony accounted for 70% share. However, with the other suppliers, the rapid growth of Sony's share will drop to 50%.
Mr. Zhou ATL believes that the advantage of foreign suppliers start early, high profile, but very expensive; domestic suppliers start later, as foreign suppliers of well-known, but the price is relatively low.
Guo Chuntai believe that the advantages of domestic suppliers at a competitive price, but in reputation, brand consistency, such as batteries and the gap between foreign suppliers. He stressed: "Chinese enterprises need to continuously improve the battery performance and quality, control costs, price competition alone can not win."
ATL Mr. Zhou stressed that the poly in place of the conventional lithium battery lithium dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery is the general trend, the current need for more manufacturers to join the camp.
