Alkaline battery cells comprising an anode, a cathode, a separator between the anode and the cathode, and an electrolyte are provided with an n-type metal oxide additive that improves electrochemical performance. The n-type metal oxide additive is either a doped metal oxide comprising a metal oxide modified by incorporation of a dopant, or a reduced metal oxide. The metal oxide may be selected from the group consisting of BaTiO3, K2TiO3, CoTiO3, SrTiO3, CaTiO3, MgTiO3, SiO2, CaO, TiO2, CoO, Co3O4, ZnO, SnO, SnO2, PbO2, Bi2O3, Bi2O3•3ZrO3, Bi12TiO20, Fe2O3-TiO2, Nb2O5, CaWO4, ZnMn2O4, and K2Cr2O7. Examples of dopant disclosed are: NbO2, Nb2O5, Ta2O5, WO3, GeO2, ZrO2, SnO2, ThO2, Fe2O3, In2O3, LiNiO2, and P2O5, In2O3, Sb2O5. |
