Abstract
The present application relates to a method comprising: (a) providing a battery comprising a manganese oxide composition as a primary active material; and (b) cycling the battery by: (i) galvanostatically discharging the battery to a first Vcell; (ii) galvanostatically charging the battery to a second Vcell; and (iii) potentiostatically charging at the second Vcell for a first defined period of time. The present application also relates to a chemical composition produced by the method above. The present application also relates to a battery comprising one or more chemical species, the one or more chemical species produced by cycling an activated composition.

A method for preparing a zinc-manganese battery, the method comprising:
- (a) chemically treating an alkali metal manganese (III, IV) oxide, thereby producing a chemically treated alkali metal manganese (III, IV) oxide;
- (b) providing the chemically treated alkali metal manganese (III, IV) oxide as an active material in a cathode of the zinc-manganese battery, the zinc-manganese battery further comprising:
- an anode and an electrolytic solution in fluid communication with the anode and the cathode;
- and
- (c) cycling the zinc-manganese battery by:
- (i) discharging the zinc-manganese battery to a first Vcell;
- (ii) charging the zinc-manganese battery to a second Vcell;
- and (iii) charging at the second Vcell for a first defined period of time.
