Rechargeable alkaline manganese dioxide-zinc bipolar batteries

A bipolar battery having at least two electrochemical cells electrically arranged in series, the bipolar battery comprising:

• a housing;
• an electrolyte disposed in the housing;
• a bipolar electrode disposed in the housing, wherein the bipolar electrode comprises:
• a first anode material;
• and
• a first cathode material, wherein the first cathode material and the first anode material are disposed on opposite faces of a current collector;
• an anode disposed in the housing, wherein the anode comprises a second anode material comprising:
• zinc and a binder;
• a cathode disposed in the housing, wherein the cathode comprises a second cathode material comprising:
• an active material comprising a manganese oxide, and additives comprising a conductive carbon and a copper compound, wherein the first cathode material of the bipolar electrode faces the second anode material, and wherein the first anode material of the bipolar electrode faces the second cathode material;
• a first microporous separator disposed between the first cathode material and the second anode material;
• and
• a second microporous separator disposed between the first anode material and the second cathode material, where the at least two electrochemical cells are formed from cathode-anode pairs, and wherein a first electrochemical cell of the at least two electrochemical cells is fluidly sealed from a second electrochemical cell of the at least two electrochemical cells.
