The unique double-sided rib design is used in the automobile type double-sided rib diaphragm, which increases the mechanical strength and stiffness of PE diaphragm, reduces the diaphragm deformation caused in the process of battery assembly, and avoids the direct pressing and bonding of the electrode plate to the diaphragm substrate, so as to effectively remove or reduce the problems of thermal oxidation and lead dendrite penetration of PE diaphragm.
