1. Solid polymer electrolyte lithium battery. The electrolyte is a mixture of polymer and salt, which is low in ionic conductivity at ambient temperature and is suitable for high-temperature use.
2. Gel polymer electrolyte lithium battery. That is to add plasticizer and other additives in the solid polymer electrolyte, so as to improve the ionic conductivity, so that the battery can be used at room temperature.
3. Lithium batteries for polymer cathode materials. The use of conductive polymers as cathode materials, the energy is 3 times times the existing lithium battery, is the latest generation of lithium batteries.
Since the liquid electrolyte is replaced with a solid electrolyte, compared with liquid lithium battery, the polymer lithium battery has the advantages of thin shape, arbitrary area and arbitrary shape, and it will not produce the safety problems such as leakage and combustion explosion, so it can make the battery shell with aluminum-plastic composite film, which can improve the capacity of the whole battery. Polymer lithium battery can also be used as a cathode material, its mass than energy will be higher than the current liquid lithium battery 50%.
