| 摘要 | A particle, including: a plurality of crystallites including a first composition having a layered α-NaFeO2-type structure and including 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 in an amount of about 1.7 to about 2.3 moles, per mole of the first composition; and a grain boundary between adjacent crystallites of the plurality of crystallites and including a second composition having the layered α-NaFeO2-type structure, a cubic structure, or a combination thereof, wherein a concentration of cobalt in the grain boundary is greater than a concentration of cobalt in the crystallites. | ||
