Abstract
A particulate precursor compound for manufacturing a lithium transition metal oxide powder for use as an active positive electrode material in lithium-ion batteries, the precursor having the general formula NiMnCoAO(OH), wherein 0.15<v<0.30, v+w=2, 0.30≤x≤0.75, 0.10≤y≤0.40, 0.10≤z≤0.40, A being a dopant with a≤0.05, and x+y+z+a=1, the precursor consisting of a crystal structure having an XRD pattern with twin peaks at 2θ=38±0.5°, the twin peaks having a left peak having a peak intensity Iand a right peak having a peak intensity I, and a peak intensity ratio R=I/Iwith R>0.7, and the XRD pattern being free of peaks belonging to either one or both of a spinel and an oxyhydroxide compound.
