Process for making an at least partially coated electrode active material wherein said process comprises the following steps: (a) Providing an electrode active material according to general formula LiTMO, wherein TM is a combination of Ni and Co or Ni and Al and, optionally, Mn, and, optionally, at least one metal selected from Ga, Nb, Ta, Mg, Mo, B, Sn, V, W, Ti and Zr, and x is in the range of from zero to 0.2, (b) treating said electrode active material with at least one carbonyl compound of Co, and (c) treating the material obtained in step (b) with an oxidant.

Process for making an at least partially coated electrode active material

Process for modifying an electrode active material according to general formula LiTMO2, 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 LiTMO2 with an aqueous medium with a pH value of at least 5 and up to 14, (b) removing said aqueous medium from treated LiTMO2 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.
