Features of Lithium Polymer Batteries

2022-02-21
Lithium polymer battery (Li-polymer, also known as polymer lithium battery): It has many obvious advantages such as high energy density, smaller size, ultra-thinness, light weight, high safety, and low cost. It is a new type of battery. Battery. In terms of shape, lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness that this type of battery can achieve can reach 0.4mm. Compared with lithium ion batteries, the characteristics of lithium polymer batteries are as follows:

1. There is no battery leakage problem, the battery does not contain liquid electrolyte, and uses colloidal solids.
2. It can be made into a thin battery: with a capacity of 3.6V400mAh, its thickness can be as thin as 0.4mm.
3. The battery can be designed into various shapes.
4. The battery can be bent and deformed: the polymer battery can be bent at a maximum of about 90°.
5. It can be made into a single high voltage: the battery with liquid electrolyte can only obtain high voltage by connecting several batteries in series, while the polymer battery can be made into a multi-layer combination in a single cell to achieve high voltage because it has no liquid itself.
6. The capacity of lithium polymer battery is twice higher than that of lithium ion battery of the same size.
