Estimating the term…
A battery treatment method for an all-solid-state battery including a positive electrode, a negative electrode, and a sulfide-based solid electrolyte, with the positive electrode having a positive electrode mixture including a positive electrode active material, the all-solid-state battery being formed using a copper member, the battery treatment method including: a deactivation step of deactivating contents of the target battery under a condition facilitating sulfidation of the copper member; a separation step of separating the positive electrode mixture from a material constituting the positive electrode; a treatment step of forming a slurry including the positive electrode mixture separated in the separation step; a flotation separation step of removing, from the slurry, solid content originating from the copper member through flotation separation; and a recovery step of recovering the positive electrode active material from the slurry from which the solid content is removed in the flotation separation step.
A battery treatment method for an all-solid-state battery as a target battery, the all-solid-state battery including a positive electrode, a negative electrode, and a sulfide-based solid electrolyte, with the positive electrode having a positive electrode mixture including a positive electrode active material, the all-solid-state battery being formed using a copper member, the battery treatment method comprising:
