Abstract: Process for making a particulate compound according to general formula Li 1+x TM 1-x O 2 with x being in the range of from -0.02 to +0.15 and with TM representing nickel and at least one metal selected from Co and Mn and, optionally, including at least one of Al, Mg, Ti, Zr, Nb, Ta, Mo, and W, wherein said process comprises the steps of:
(a) providing a nanoparticulate oxide or (oxy)hydroxide of each of the metals of TM,
(b) mixing the nanoparticulate oxides or (oxy)hydroxides in the stoichiometry targeted for TM under addition of a source of lithium selected from LiOH and Li 2 CO 3 and Li 2 O 2 and Li 2 O, and
(c) treating the mixture from step (c) at a temperature in the range of from 700 to 950°C.
