Abstract:
1. A particle, comprising: a plurality of crystallites comprising a first composition having a layered α-NaFeO lithium in an amount of about 0.1 to about 1.3 moles, per mole of the first composition, nickel in an amount of about 0.1 to about 0.79 mole, per mole of the first composition, cobalt in an amount of 0 to about 0.5 mole, per mole of the first composition, and oxygen; and a grain boundary between adjacent crystallites of the plurality of crystallites and comprising a second composition having the layered α-NaFeO wherein a concentration of cobalt in the grain boundary is greater than a concentration of cobalt in the crystallites.
