Abstract
A method for recycling a cathode material and a solid electrolyte from a solid-state lithium battery is provided. The method has the following steps: a) separating the solid-state lithium battery into a solid mixture, said mixture comprising lithium anode, cathode material, and solid electrolyte components, b) mixing the solid mixture with an aprotic solvent, forming a solution of the solid electrolyte in the aprotic solvent and insoluble constituents comprising lithium anode and cathode material, c) separating the solution of the solid electrolyte from the insoluble constituents, d) bringing the insoluble constituents into contact with a protic solvent, forming a solution of lithium salt of the general formula LiX in the protic solvent and undissolved cathode material, e) separating the solution of lithium salt LiX from the undissolved cathode material, and f) calcinating the separated cathode material while adding a lithium compound.
