Abstract
A crystalline precursor compound 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 M(O)(OH)(CO), with 0<x≤1, 0<y<0.03 and M=NiMnCoA. A being a dopant, with 0.30≤a<0.90, 0.10≤b<0.40, 0.10≤c<0.40, d<0.05 and a+b+c+d=1, the precursor having a Na content less than 200 ppm, a S content less than 250 ppm, the precursor having a specific surface area with a BET value expressed in m/g and a tap density TD expressed in g/cm, with a ratio BET/TD>30.10cm/g.
