METHOD FOR PRODUCING HIGH NICKEL LITHIATED METAL OXIDE FOR BATTERY

A method for preparing high nickel lithiated metal oxides that includes selecting one or more nickel precursors; at least one non-corrosive lithium salt; and a plurality of metal oxide or hydroxide precursors. The metal precursors and lithium salts are mixed together to form a mixture comprising: wherein x = 1.0 - 1.1, 0.80 ≤ y ≤ 0.90, 0.03 < z ≤ 0.15, and 0 ≤ a ≤ 0.05; M is Co or Fe; and N is Al, Mn, Fe, Ca, Mg, Ti, Cr, Nb, Mo, W, B, or a mixture thereof provided N may be Fe when M is Co. The mixture is subjected to sintering (1 step) in air at ≥ 750° C. to form a powder. The powder is subjected to a 2 sintering step in O at ≤ 750° C. to form the high nickel lithiated metal oxides.
