Lithium Battery Description:

Lithium-ion polymer batteries are generally named with 6 digits, indicating thickness/width/height respectively. For example, PL803040 indicates a lithium-ion polymer battery with a thickness of 8.0mm, a width of 30mm and a height of 40mm, where PL indicates the battery It belongs to the polymer category. The production process of lithium-ion polymer batteries generally adopts laminated flexible packaging, so the size change is very flexible and convenient, and there are relatively many models.

Polymer batteries: generally use soft aluminum-plastic composite packaging film. The interior is a semi-solid polymer. The performance is stable in discharge, high in efficiency and small in internal resistance. The safety performance is good, and there are overcurrent and overvoltage protection devices. The service life is about 500 charge-discharge cycles. However, polymer batteries are usually packaged with tin foil, which is easy to deform, not resistant to impact, and the quality of overvoltage protection is good or bad due to different manufacturers.

Polymer lithium batteries are generally made of lithium cobalt oxide, lithium manganate, and ternary lithium as raw materials. Through a certain proportion of the mixture of the three, it is produced by a certain process. The outer packaging is mainly made of aluminum plastic film, and the lithium material in the middle is paste. So the shape can be customized arbitrarily. At the same time, ultra-thin batteries can be produced, such as ultra-thin batteries of 0.33mm and 0.50mm.


  • This battery cannot mix with deposal or twice-recycled batteries in use. Otherwise, for its abnormal charge and discharge, it will cause overheating, distortion, smoking or burning.
  • Keep the battery out of children’s reach and prevent them biting or swallowing the battery.
  • Do not insert the battery into the charger for a long time. If charging beyond the normal time, the battery is still in the charger, please stop charging. The abnormal charging will cause overheating, distortion, smoking or burning.
  • Do not put the battery into microwave oven or any other pressure apparatus. Take the battery away from the cellular phone or the charger if it is instant heated or leak-out (or odors), and then depose it. Using the bad battery will causes overheating, distortion, smoking or burning.


  • What’s MOQ of buld order?
    We can accept small orders at beginning.
  • What’s the product warranty?
    1 year after batteries were sent out.
  • How long will customers receive samples?
    7~15 days once the datasheet confirmed.
