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:LiNiMNOFa  (F-1)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 (1st step) in air at ≥750° C. to form a powder. The powder is subjected to a 2sintering step in Oat ≤750° C. to form the high nickel lithiated metal oxides.
