Features of Polymer Li-Ion Batteries

Polymer li-Ion battery, also known as polymer lithium battery, is a chemical battery. Compared with the previous battery, it has the characteristics of high energy, miniaturization and light weight.
Polymer li-Ion batteries use file alloys as positive electrodes, polymer conductive materials, polyacetylene, polyaniline or poly-p-phenol as negative electrodes, and organic solvents as electrolytes. The specific energy of Polymer Li-Ion Battery can reach 350W.h/kg, but the specific power is only 50-60W/kg, the operating temperature is -40-70 degrees, and the service life is about 330 times.
Compared with lithium-ion batteries, Polymer li-Ion batteries have the following characteristics:
1. The problem of battery leakage is relatively improved, but it has not been completely improved.
2. It can be made into a thin battery: with a capacity of 3.6V 250mAh, its thickness can be as thin as 0.5mm.
3. The battery can be designed into various shapes.
4. 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.

5. The discharge capacity is theoretically 10% higher than that of a lithium-ion battery of the same size.
