Abstract:
A crystalline precursor compound is described for manufacturing a lithium transition metal based oxide powder usable as an active positive electrode material in lithium-ion batteries, the precursor having a general formula Li 1−a  ((Ni z (Ni 1/2  Mn 1/2 )y Co x ) 1−k  A k ) 1+a  O 2 , wherein x+y+z=1, 0.1≤x≤0.4, 0.25≤z≤0.55, A is a dopant, 0≤k≤0.1, and 0.04≤a≤0.50, wherein the pre cursor has a crystalline size L expressed in nm, with 77−(67*z)≤L≤97−(67*z). Also a method is described for manufacturing a positive electrode material having a general formula Li 1−a′  ((Ni z  (Ni 1/2  Mn 1/2 ) y  A k ) 1−a′  O 2 , wherein x+y+z=1, 0.1≤x≤0.4, 0.25≤z≤0.55, A is a dopant, 0≤k≤0.1, and 0.01≤a′≤0.10 by sintering the crystalline precursor compound in an oxidizing atmosphere at a temperature T between 800 and 1000° C., for a time t between 6 and 36 hrs.

Claim (Index 31):
A positive electrode material having a general formula Li 1+a\u2032  ((Ni z  (Ni 1/2  Mn 1/2 ) y  CO x ) 1\u2212k  A k ) 1\u2212a\u2032 O 2 , wherein x+y+z=1, 0.1\u2264x\u22640.4, 0.25\u2264z\u22640.55, A is a dopant, 0\u2264k\u22640.1, and 0.01\u2264a\u2032\u22640.10, wherein the positive electrode material is prepared by two successive lithiation reactions, wherein the first lithiation reaction yields an intermediate compound that is lithium deficient versus the positive electrode material.
