The invention relates to a LiaNixCoyMny'M'zO2 composite oxide for use as a cathode material in a rechargeable battery, with a non-homogenous Ni/M' ratio in the particles, allowing excellent power and safety properties when used as positive electrode material in Li battery. More particularly, in the formula 0.9 < a < 1.1, 0.3 ≤ x ≤ 0.9, 0 < y ≤ 0.4, 0 < y' ≤ 0.4, 0 < z ≤ 0.35, e < 0.02, 0 ≤ f ≤ 0.05 and 0.9 < (x+y+y'+z+f) < 1.1; M' consists of either one or more elements from the group Al, Mg, Ti, Cr, V, Fe, Mn and Ga; N consists of either one or more elements from the group F, Cl, S, Zr, Ba, Y, Ca, B, Sn, Sb, Na and Zn. The powder has a particle size distribution defining a D10, D50 and D90; and the x and z parameters varying with the particles size of the powder, and is characterized in that either one or both of: x1 - x2 ≥ 0.005 and z2 - z1 ≥ 0.005; x1 and z1 being the parameters corresponding to particles having a particle size D90; and x2 and z2 being the parameters corresponding to particles having a particle size D10.
