Abstract: Described herein are acidified metal oxide (“AMO”) materials useful in applications such as a battery electrode or photovoltaic component, in which the AMO material is used in conjunction with one or more acidic species. Advantageously, batteries constructed of AMO materials and incorporating acidic species, such as in the electrode or electrolyte components of the battery exhibit improved capacity as compared to a corresponding battery lacking the acidic species.
