Abstract:
1. A method of making a cathode active material, comprising the steps of: combining an alkali-containing compound, a nickel-containing compound, one or more metal-containing compounds, and one or more non metal-containing compounds at a stoichiometric ratio of from 1:0.98:0.02:0 to 1:0.86:0.12:0.02 to form a mixture; heating the mixture at a first temperature above at least about 185° C. in flowing oxygen or an oxygen-enriched atmosphere for a first duration; cooling the mixture to at least about 40° C. in flowing oxygen or an oxygen-enriched atmosphere; heating the mixture at a second temperature above at least about 775° C. in flowing oxygen or an oxygen-enriched atmosphere for a second duration to form a ANi treating the ANi
