    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.

    Abstract: The present invention is in the field of processes for the generation of thin inorganic films on substrates, in particular atomic layer deposition processes. The present invention relates to a process for the generation of inorganic films comprising depositing the compound of general formula (I) onto a solid substrate (I), wherein M is Mn, Ni or Co, X is a ligand which coordinates M, n is 0, 1, 2, 3, or 4, R1 is an alkyl group, an alkenyl group, an aryl group, a halogen, or a silyl group, R2 is an alkyl group, an alkenyl group, an aryl group, or a silyl group, p and q are 1 or 2, wherein p+q=3, and m is 1, 2, or 3.

    Abstract: A process for the recovery of 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 Mn, 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, and at least a fraction of said Mn, if present, is manganese(II)oxide; which particulate material further contains a lithium salt and a fluoride salt, and which particulate material optionally contains calcium provided that the element ratio calcium to fluorine is 1.7 or less or is zero; (b) treating the material provided in step (a) with a polar solvent and an alkaline earth hydroxide; and (c) separating the solids from the liquid, optionally followed by washing the solid residue with a polar solvent such as water provides good separation of lithium in high purity, and recovery of valuable transition metals.
