High precision lithium battery diaphragm
Page view:

In the structure of lithium battery, the diaphragm is one of the key inner components. The performance of the diaphragm 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 overall performance of the battery. The main function of the separator is to separate the positive and negative electrodes of the battery to prevent short circuits caused by the contact between the two electrodes. In addition, it also has the function of making the electrolyte ions pass through.

The product has the characteristics of high porosity, high thermal resistance, high melting point, high strength and good infiltration to the electrolyte.
