Coating compositions for electrode compositions and their methods of making
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 LiCoO.sub.2, LiMn.sub.2O.sub.4, Li.sub.2MnO.sub.3, LiNiO.sub.2, LiMn.sub.1.5Ni.sub.0.5O.sub.4, LiFePO.sub.4, Li.sub.2FePO.sub.4F, Li.sub.3CoNiMnO.sub.6, Li(Li.sub.aNi.sub.xMn.sub.yCo.sub.z)O.sub.2, 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.
