Classification of lithium-ion polymer batteries

1. Solid polymer electrolyte lithium-ion battery: The solid polymer electrolyte lithium-ion battery electrolyte is a mixture of polymer and salt. This battery has low ion conductivity at room temperature and can be used at room temperature.

2. Gel polymer electrolyte lithium-ion battery: Gel polymer electrolyte lithium-ion battery is to add plasticizer and other additives to the solid polymer electrolyte to improve the ion conductivity and make the battery can be used at room temperature.



3. Polymer lithium-ion battery: The lithium-ion battery of polymer cathode material uses conductive polymer as the cathode material, and its specific capacity is relatively increased. Since the solid electrolyte is used instead of the liquid electrolyte, compared with the liquid lithium-ion battery, the polymer lithium-ion battery has the advantages of thinning, arbitrary area and arbitrary shape, so the battery casing can be made of aluminum-plastic composite film, thereby It can improve the specific capacity of the entire battery; the polymer lithium ion battery can also use polymers as the positive electrode material, and its mass specific energy will increase by more than 20% compared with the current liquid lithium ion battery. Polymer lithium-ion batteries have the characteristics of miniaturization, thinning and light weight. Therefore, the market share of polymer batteries will gradually increase.
