Lipo is a lithium polymer battery.
Lithium polymer battery (Li-polymer, also known as lithium polymer battery). Lithium polymer battery refers to a lithium-ion battery that uses a polymer as the electrolyte. “semi-polymer battery” and “semi-polymer battery”. There are two types: “polymer” and “all-polymer”.
“Semi-polymer” refers to the coating of a layer of polymer (usually PVDF) on the insulating film to strengthen the adhesion of the cell, the battery can be made harder and its electrolyte is always a liquid electrolyte. “Full polymer” refers to using polymers to form a gel network inside the battery core and then injecting electrolyte to form an electrolyte.
Although “all-polymer” batteries still use liquid electrolyte, the amount used is much less, which improves performance.considerably the safety performance of lithium-ion batteries. To the author's knowledge, only SONY currently mass-produces "all-polymer" lithium-ion batteries.
Detailed information:
Compared to lithium-ion batteries, the characteristics of lithium polymer batteries As follows:
1. Relatively, the battery leakage problem has been improved, but it has not been completely improved.
2. It can be transformed into a thin battery: with a capacity of 3.6 V 250 mAh, its thickness can reach 0.5 mm.
3. Batteries can be designed in different shapes.
4. Can be made into a single high-voltage battery: Liquid electrolyte batteries can only obtain high voltage by connecting multiple batteries in series, while polymer batteries can be made into multiple layers in a single battery because elhave no liquid combination to reach high voltage.
