Patent ID: 11404748

Abstract:
An electrode-separator assembly is provided that can drastically facilitate assembly of a LDH separator-equipped nickel-zinc battery without the work, structure, or components for the complete separation of a positive-electrode chamber from a negative-electrode chamber. The electrode-separator assembly includes a positive-electrode plate, a negative-electrode plate, a layered double hydroxide (LDH) separator for separation of the positive-electrode plate from the negative-electrode plate, and a resin frame having an opening to which the LDH separator and the positive-electrode plate are fitted or joined. The positive-electrode plate has a smaller face than the negative-electrode plate. The negative-electrode plate has a clearance area that does not overlap with the positive-electrode plate over a predetermined width from the outer peripheral edge of the negative-electrode plate. The peripheral end faces of the LDH separator, and a segment of the separator adjacent to the positive-electrode plate and corresponding to the clearance area, are covered with the resin frame.
