ABSTRACT:
A method of manufacturing an electrochemical cell is described. A separator sheet segregating the anode from direct contact with the cathode is folded back upon itself along a crease with an upper portion at least partially sealed to a lower portion along an aligned peripheral edge to form an envelope. A first envelope portion houses the cathode having an uncovered portion of the cathode current collector spaced from the crease and a second envelope portion houses the anode. The first envelope portion is sealed to the second envelope portion through uncovered perforations of the cathode current collector to lock the anode aligned with the cathode. The anode and cathode are then wound into a jellyroll electrode assembly housed in a cylindrical casing and activated with an electrolyte.
