Lithium Polymer Battery Advantages&Disadvantages


The safety performance of polymer li-ion battery is higher than that of traditional li-ion battery. The battery cell has international certification such as ul and ce, which has high quality and safe and reliable guarantee. After the initial test of the polymer lithium ion is successful, it has been widely used in various mobile digital products of world famous manufacturers such as ipod, samsung, lg and moto.



In addition to these mature digital devices, polymer lithium batteries are also used in some new high-tech products.



It is imperative that polymer lithium batteries become mainstream. Polymer lithium batteries have advantages over traditional liquid lithium batteries in terms of safety, volume, weight, capacity and discharge performance. In the past, domestic and foreign manufacturers of polymer lithium ion batteries mostly adopted bellcore technology produced by bell laboratories in the United States. However, the development and industrialization of polymer li-ion batteries are seriously restricted by the disadvantages of complicated process, low efficiency, large equipment investment and high production cost.



It is worth mentioning that because the material used in the polymer cell has sufficient safety itself, PTC and fuse are omitted in the design of the protective circuit of the battery, thus saving the battery cost. In addition, the internal resistance of polymer cells is smaller than that of liquid cells, which greatly reduces the battery's self-consumption and extends the standby time of digital products to some extent. In addition, the polylithium battery can be designed in any shape, and the thickness of the cell can be increased or reduced according to the demands of customers. Some can even be customized according to the shape of mobile phones, digital cameras and so on, so as to make full use of the battery shell space and improve the battery capacity. It also has no leakage, no heavy metal, no pollution and other environmental features. At present, the use of polymer cells is rapidly increasing and quietly popular, becoming an indispensable ideal for mobile life.


in a word, lithium ion batteries, either li ion in cylinderic shap, like 18650, 21700 type, or lithium polymer type, each has it's typical application because of it's special characteristic.
