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.

The present application also relates to a chemical composition produced by the method above. The present application also relates to a battery comprising a chemical composition having an X-ray diffractogram pattern expressing a Bragg peak at about 26°, said peak being of greatest intensity in comparison to other expressed Bragg peaks. 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.
