For lithium battery series, because the electrolyte is an organic solvent system, it is necessary to have a separator material resistant to organic solvents, and generally a high-strength thin polyolefin porous membrane is used. The separator of lithium-ion battery has a large number of zigzag micropores, which can ensure the free passage of electrolyte ions to form a charge-discharge circuit; However, when the battery is overcharged or the temperature rises, the diaphragm separates the anode and cathode of the battery through the obturator function to prevent direct contact and short circuit, so as to block current conduction and prevent the battery from overheating or even explosion.
