Title:
電池部材の処理方法
Document Type and Number:
Japanese Patent JP5062262
Kind Code:
B2
Abstract:
It is a major object of the invention to provide a method for processing a battery member, by which a cathode active material and a sulfide solid electrolyte material can be efficiently separated from each other and the cathode active material and Li contained in the sulfide solid electrolyte material can be efficiently recovered. To achieve the object, the present invention provides a method for processing a battery member containing at least a Li-containing cathode active material and a Li-containing sulfide solid electrolyte material, comprising the steps of: bringing the battery member into contact with a process solution to generate hydrogen sulfide as well as to dissolve the Li contained in the sulfide solid electrolyte material in the process solution; recovering the cathode active material as an insoluble component from the process solution containing the Li dissolved therein; and recovering a Li compound from the process solution, from which the cathode active material as an insoluble component is recovered.
