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 33):
