The diaphragm with excellent performance plays an important role in improving the comprehensive performance of the battery. The main function of the diaphragm is to separate the positive and negative electrodes of the battery to prevent short circuit caused by contact between the two electrodes. In addition, it also has the function of allowing electrolyte ions to pass through. The diaphragm material is not conductive, and its physical and chemical properties have a great influence on the performance of the battery. Different types of batteries use different diaphragms. For lithium battery series, since the electrolyte is an organic solvent system, a diaphragm material resistant to organic solvents is required. Generally, high-strength thin polyolefin porous membrane is used.
