Analysis of classification and characteristics of polymer lithium batteries

Solid polymer electrolyte lithium battery electrolyte is a mixture of polymer and salt. This battery has low ionic conductivity at room temperature and can be used at room temperature. Gel-gel polymer electrolyte lithium batteries add plasticizers and other additives to the solid polymer electrolyte to improve ionic conductivity and allow the battery to be used at room temperature. Lithium batteries using polymer polymer cathode materials use conductive polymers as cathode materials, and their specific capacity is relatively new. Since the solid electrolyte is used instead of the liquid electrolyte, compared with the liquid lithium battery, the polymer lithium battery has the advantages of thinning, arbitrary area and arbitrary shape, so the battery casing can be made of aluminum-plastic composite film, which can improve The specific capacity of the entire battery; polymer lithium batteries can also use polymers as the positive electrode material, and its mass specific energy will be more than 20% higher than the current liquid lithium batteries. The polymer lithium ion (PolymerLithium-IonBattery) battery has the characteristics of miniaturization, thinning, and light weight. Therefore, the market share of polymer batteries will gradually increase. 2 Features Polymer lithium battery has the following characteristics [2]: ① shaping flexibility; ② higher mass specific energy (3 times that of MH-Ni battery); ③ wide electrochemical stability window, up to 5V; ④ perfect Safety and reliability; ⑤Longer cycle life, less capacity loss; ⑥High volume utilization; ⑦Wide range of use.
