Polymer li-Ion batteries
have ultra-thin characteristics, and can be made into batteries of different shapes and capacities to meet the needs of some products. The theoretical minimum thickness can reach 0.5mm. Polymer li-Ion batteries
can be divided into three categories according to the electrolyte:
1. Gel polymer electrolyte lithium ion battery, which is to add additives to the solid polymer electrolyte to improve the ionic conductivity, so that the battery can be used at room temperature;
2. Solid polymer electrolyte lithium ion battery, the electrolyte is a mixture of polymer and salt, the ionic conductivity at room temperature is low, and it is suitable for high temperature use;
3. Lithium-ion battery with composite gel polymer cathode material, conductive polymer as cathode material, its specific energy is 3 times that of existing lithium-ion battery, it is the latest generation of lithium-ion battery.
