Abstract:
Compositions and methods of making are provided for coated electrodes and batteries comprising the same. The compositions may comprise a base composition having an active material selected from the group consisting of LiCoO2, LiMn2O4, Li2MnO3, LiNiO2, LiMn1.5Ni0.5O4, LiFePO4, Li2FePO4F, Li3CoNiMnO6, Li(LiaNixMnyCoz)O2, and mixtures thereof. The compositions may also comprise a coating composition that covers at least a portion of the base composition, wherein the coating composition comprises a non-metal or metalloid element. The methods of making comprise providing the base composition and a doped carbon coating composition, and mixing the coating composition with the base electrode composition at an elevated temperature in a flowing inert gas atmosphere. The coating composition may be a nitrogen-doped carbon composition a nitrogen doping element selected from the group consisting of: pyridine, 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, 1-ethyl-3-methylimidazolium dicyanamide, and mixtures thereof.
