Title: Surface modifications for electrode compositions and their methods of making

Abstract

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.
