Abstract: The invention discloses a method of manufacturing an electrochemical cell having a polymer separator membrane for separation of electrodes in the electrochemical cell, including providing a cathode and providing a polymer separator membrane. At least one cycle of irradiating the polymer separator membrane is performed by an energy beam under a radiation dose ranging between 50 and 200 kGy to effect a cross-linking in the polymer separator membrane. The polymer separator membrane is maintained at a temperature between 30° C. and 70° C. An anode is then provided. Subsequently, the polymer separator membrane is compressed between the cathode and the anode. An electrolyte is provided to form the electrochemical cell.
