    Abstract: Process for modifying an electrode active material according to general formula Li 1+x TM 1-x O2, wherein TM contains a combination of Ni and at least one transition metal selected from Co and Mn, and, optionally, at least one metal selected from Al, Ba, and Mg and, optionally, one or more transition metals other than Ni, Co, and Mn, wherein at least 75 mole-% of TM is Ni, and x is in the range of from -0.05 to 0.2, said process comprising the steps of (a) treating said Li 1+x TM 1-x O2 with an aqueous medium with a pH value of at least 5 and up to 14, (b) removing said aqueous medium from treated Li 1+x TM 1-x O2 by way of a solid-liquid separation, wherein steps (a) and (b) are commenced with a maximum time difference of 3 minutes. In addition, the present invention is directed towards Ni-rich electrode active materials.

    IPC: C01G53/00

    Abstract: Process for the manufacture of a fluoride doped cathode active material wherein said process comprises the steps of (a) providing a particulate oxide or (oxy)hydroxide of TM wherein TM comprises nickel and at least one metal selected from cobalt and manganese, wherein said particulate oxide or (oxy)hydroxide has an average particle diameter (D50) in the range of from 3 to 16 µm, (b) providing a source of lithium that contains 0.01 to 2.5 % by weight of fluoride, uniformly dispersed within said source of lithium, (c) mixing said oxide or (oxy)hydroxide of TM with said fluoride-containing source of lithium and, optionally, with additional source of lithium containing less fluoride, and, optionally, with one or more dopants based on at least one metal other than lithium, (d) treating the mixture obtained from step (c) thermally.
