The feature of the lithium polymer battery(1)

2021-11-20
Lithium polymer battery uses file alloy as positive electrode, polymer conductive material, polyacetylene, polyaniline or poly-p-phenol as negative electrode, and organic solvent as electrolyte. The specific energy of lithium polyaniline battery can reach 350w.h/kg, but the specific power is only 50-60w/kg, the service temperature is - 40-70 ℃, and the service life is about 330 times.

Compared with lithium ion batteries, lithium polymer batteries have the following characteristics:
1. The problem of battery leakage was relatively improved, but it was not completely improved.(lithium polymer battery)

2. It can be made into thin battery: with a capacity of 3.6V 250mah, its thickness can be as thin as 0.5mm.(lithium polymer battery)

3. Batteries can be designed in a variety of 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 multi-layer combination in a single battery to achieve high voltage because it has no liquid.

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