The present invention comprises steps of: forming an opening portion (38') in a battery case (12) (time point t1 to time point t5); aspirating an electrolyte solution from the interior of the battery case (12) through the opening portion (38´) and into a sealed and depressurized electrolyte solution recovery trap (64) (time point t5 to time point t6); injecting a solvent containing no electrolyte from a solvent tank (62) through the opening portion (38'), and into the battery case (12) (time point t8 to time point t9); and aspirating a mixed solution from the interior of the battery case (12) through the opening portion (38') and into the sealed and depressurized electrolyte solution recovery trap (64) (time point t10 to time point t11). By performing the above-mentioned process, battery constitutive members including the battery case (12) can be disassembled and recovered efficiently in large quantities. |
