POLYCRYSTALLINE METAL OXIDE, METHODS OF MANUFACTURE THEREOF, AND ARTICLES COMPRISING THE SAME
A particle comprising a plurality of lithium nickel oxide crystallites having a layered alpha-NaFeO2-type structure, and a grain boundary between adjacent crystallites;wherein the concentration of cobalt in the lithium nickel oxide crystallites is 0 atomic percent or cobalt is uniformly distributed in the lithium nickel oxide crystallites; and wherein the grain boundary is on the surface of the crystallite and comprises a second composition comprising a Co-substituted lithium nickel oxide having a layered alpha-NaFeO2-type structure, a cubic structure or a combination thereof, and wherein the concentration of cobalt in the grain boundaries is greater than the concentration of cobalt in the crystallites.
