Consumer battery diaphragm high in safety
A battery separator and consumer technology, applied in the field of battery materials, can solve the problems of affecting the battery cycle life, poor air permeability of the polyolefin separator, unable to meet the fast charging and discharging of the battery, etc., and achieves low oxidation resistance and hydrophilicity. Good, small aperture effect
