Lithium-ion battery separator pelletizing machine
In simple terms, the membrane is a porous plastic film made of basic materials such as PP and PE and additives. Its main role in lithium-ion batteries is to maintain insulation between the positive and negative electrodes as lithium ions shuttle between them to prevent short circuits. Therefore, an important performance index of the film is its heat resistance, which is expressed by its melting point. At present, most film manufacturers in the world use the wet method, that is, the film is stretched with solvent and plasticizer, and then the pores are formed by solvent evaporation. The highest melting point of the wet-process PE lithium-ion battery separator launched by Tonen Chemical in Japan is 170°C.We can also offer the battery separator pelletizing machine. The battery separator mainly are made from the wet method.
