Abstract: Described herein is a process for the manufacture of a fluoride doped cathode active material, where said process includes the steps of
(a) providing a particulate oxide or (oxy)hydroxide of transition metals (TM), where TM includes nickel and at least one metal selected from cobalt and manganese, and where said particulate oxide or (oxy)hydroxide has an average particle diameter (D50) in a range of from 3 to 16 μm,
(b) providing a source of lithium that includes 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-including source of lithium and, optionally, with an additional source of lithium including less fluoride, and, optionally, with one or more dopants based on at least one metal other than lithium, and
(d) treating the mixture obtained from step (c) thermally.-

Abstract: A process for the recovery of one or more transition metals and lithium from waste lithium ion batteries or parts thereof is disclosed. The process comprising the steps of (a) providing a particulate material containing a transition metal compound and/or transition metal, wherein the transition metal is selected from the group consisting of Ni and Co, and wherein further at least a fraction of said Ni and/or Co, if present, are in an oxidation state lower than +2, e.g. in the metallic state; which particulate material further contains a lithium salt; (b) treating the material provided in step (a) with a polar solvent and optionally an alkaline earth hydroxide; (c) separating the solids from the liquid, optionally followed by a solid-solid separation step; and (d) treating the solids containing the transition metal in a way to dissolve at least part of the Ni and/or Co, typically using a mineral acid, provides good separation of lithium in high purity and of transition metal useful for the production of battery cathode active materials.
