Li-ion Battery Separator

Lithium battery separator is one of the four main materials of lithium battery, accounting for 5-10% of the material cost. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. The separator with excellent performance plays an important role in improving the comprehensive performance of the battery. The main function of the separator is to separate the positive and negative electrodes of the battery, prevent the short circuit caused by the contact between the two poles. In addition, it can make the electrolyte ions pass through. The diaphragm material is non-conductive, and its physical and chemical properties have a great impact on the performance of the battery. Different types of batteries use different separators.
