Shenzhen Baofeng New Energy Co., Ltd. - Lithium polymer battery manufacturer to tell you today how the rise of polymer lithium battery. We research and development of batteries, so the problem is very clear.
Lithium-ion batteries generally have four major components in the structure: positive, negative, electrolyte, diaphragm, shell. Spiral winding internal battery structure, with a very fine and highly permeable polyethylene film insulation material in the positive and negative intervals formed. Prior to the advent of polymer batteries, lithium batteries used to 18650 as the representative of the liquid lithium battery. However, when the market demand for thinning, 18650 of the existing market gradually eroded.
Compared with liquid lithium-ion batteries, polymer lithium-ion batteries have the advantages of thinning, arbitrary area and any shape, etc., and do not cause any safety problems such as liquid leakage and combustion explosion. Therefore, the material of the housing can be lighter , Which can improve the specific capacity of the entire battery. Currently, polymer batteries replace the 18650 and 16650 on laptops, and square batteries on smartphones. From the perspective of product design and production, the polymer has the maximum design flexibility, can be tailored to the design requirements of the end product design and production, including the production of shaped batteries, take full advantage of product space, the level of production automation is also rising Among them.
