Polymer lithium battery, also known as lithium polymer battery (Li-Po) or polymer lithium battery, is a lithium-ion battery that uses a polymer electrolyte. Compared with traditional lithium batteries (Li-ion), polymer lithium batteries have the following main features:
- High energy density: Polymer lithium batteries have a high energy density and can store more energy per unit volume or weight.
- Miniaturization and lightweight: Due to its special electrolyte form, polymer lithium batteries can be made into ultra-thin and lightweight shapes, suitable for devices with high space and weight requirements.
- Design flexibility: Polymer lithium batteries can be made into various shapes and capacities to meet the needs of different devices.
- High safety: The use of solid or gel electrolyte reduces the risk of leakage and explosion, and improves impact and puncture resistance.
- Long cycle life: Under normal conditions, the charge and discharge cycle of polymer lithium batteries can exceed 500 times.
- No memory effect: Polymer lithium batteries do not have a memory effect, that is, the battery capacity will not be reduced due to charge and discharge cycles.
- Fast Charging: Can be fully charged in one to two hours using a constant current constant voltage charger rated at 4.2V.
