Compositions and methods of making are provided for surface modified electrodes and batteries comprising the same. The compositions may comprise a base composition having an active material capable of intercalating the metal ions during a discharge cycle and deintercalating the metal ions during a charge cycle, wherein the active material is selected from the group consisting of LiCoO2, LiMn2O4, Li2MnO3, LiNiO2, LiMn1.5Ni0.5O4, LiFePO4, Li2FePO4F, Li3CoNiMnO6, Li(LiaNixMnyCoz)O2, LiaMn1.5-bNi0.5-cMdO4-x, and mixtures thereof. The compositions may also comprise an annealed composition covering a portion of the base composition, formed by a reaction of the base composition in a reducing atmosphere. The methods of making comprise providing the base composition and annealing the base electrode in a reducing atmosphere. |
