    摘要： 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.

    摘要： The invention relates to a pipeline system for a linearly concentrating solar power plant (1) with at least one receiver line (13), in which a heat transfer medium is heated by radiating solar energy, or with a central receiver and at least one emptying tank (21) and/or one store for the heat transfer medium, the heat transfer medium having a vapor pressure of less than 0.5 bar at the maximum operating temperature. Furthermore, a gas displacement system (31) is comprised, which connects gas spaces in the at least one emptying tank (21) and/or in the store for the heat transfer medium to one another and which has a central gas store (35) and/or a central gas connection (37) and a central exhaust gas outlet (39), through which gas can be discharged into the surroundings.
