United States Patent Application

View the Complete Application at the US Patent & Trademark Office
In an embodiment, a secondary Zn--MnO.sub.2 battery comprises a battery housing, a MnO.sub.2 cathode, a Zn anode, and an electrolyte solution. The MnO.sub.2 cathode, the Zn anode, and the electrolyte solution are disposed within the battery housing, and the MnO.sub.2 cathode comprises a MnO.sub.2 cathode mixture and a current collector. The MnO.sub.2 cathode mixture is in electrical contact with at least a portion of an outer surface of the current collector, and the MnO.sub.2 cathode has a porosity of from about 5 vol. % to about 90 vol. %, based on the total volume of the MnO.sub.2 cathode mixture of the MnO.sub.2 cathode.
