In an embodiment, a secondary Zn—MnObattery comprises a battery housing, a MnOcathode, a Zn anode, and an electrolyte solution. The MnOcathode, the Zn anode, and the electrolyte solution are disposed within the battery housing, and the MnOcathode comprises a MnOcathode mixture and a current collector. The MnOcathode mixture is in electrical contact with at least a portion of an outer surface of the current collector, and the MnOcathode has a porosity of from about 5 vol. % to about 90 vol. %, based on the total volume of the MnOcathode mixture of the MnOcathode.

Secondary zinc-manganese dioxide batteries for high power applications

Methods of using specific operational charge and discharge parameters to extend the life of alkaline batteries are disclosed. The methods can be used with any commercial primary or secondary alkaline battery, as well as with newer alkaline battery designs, including batteries with flowing electrolyte. The methods include cycling batteries within a narrow operating voltage window, with minimum and maximum cut-off voltages that are set based on battery characteristics and environmental conditions. The narrow voltage window decreases available capacity but allows the batteries to be cycled for hundreds or thousands of times.
