Overview of the performance characteristics of polymer lithium batteries

Lithium polymer battery overview Lithium batteries can be divided into liquid lithium batteries (LIB) and polymer lithium batteries (LIP) according to the electrolyte materials used. The polymer lithium battery and liquid lithium ion use the same positive and negative materials, and the working principle of the battery is also the same. The important difference lies in the electrolyte. Lithium batteries use liquid electrolytes, while polymer lithium batteries use solid polymer electrolytes instead. The solid polymer electrolyte can be dry or colloidal, and is currently mainly composed of polymer gel electrolyte. Polymer lithium batteries can be divided into three categories: (1) Solid electrolyte lithium batteries. The electrolyte is a mixture of polymer and salt. This battery has low ion conductivity at room temperature and is suitable for high temperature use. (2) Gel polymer electrolyte lithium battery. That is, additives such as plasticizers are added to the solid polymer electrolyte to increase the ionic conductivity, so that the battery can be used at room temperature. (3) Polymer anode material lithium battery. Using conductive polymer as the negative electrode material, its specific energy is three times that of existing lithium batteries, which is the latest generation of lithium batteries. Use solid electrolyte instead of liquid electrolyte, and liquid lithium battery, polymer lithium battery has a thin shape change, any area has any shape, etc., there will be no leakage and combustion explosion safety problems, so you can use Lu Shipingsu composite Thin-film manufacturing of battery casings can improve specific storage batteries; polymer lithium batteries can also use polymers as cathode materials, and their mass specific energy will be more than 50% higher than current liquid lithium batteries. In addition, polymer lithium batteries are better than lithium batteries in terms of operating voltage and charge-discharge cycle life. Based on the above advantages, the polymer lithium battery is called the next generation lithium battery.
