In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

There are two basic processes of internal short circuit of battery caused by metal foreign matters, as shown in Figure 1. In the first case, large metal particles directly pierce the diaphragm, causing a short circuit between the positive and negative electrodes, which is a physical short circuit.

With the popularity of electric vehicles, more and more people begin to pay attention to the battery. The battery is the energy storage warehouse of electric vehicles. Electric vehicles convert electric energy into chemical energy when charging and store it in the battery. When using electric vehicles, the motor converts the chemical energy in the battery into mechanical energy, so that electric vehicles can run on the road. Since the battery is the power source of electric vehicles, What kinds of batteries are currently used in electric vehicles and which battery is better?
