摘要： A regeneration method of an all-solid-state battery (50) includes a step of preparing an all-solid-state battery (50) having a cathode (52) that does not contain copper, and a step of executing overdischarge control of the all-solid-state battery (50). The overdischarge control is control of mitigating reaction variance that is variance in electrode reaction due to charging and discharging of the all-solid-state battery (50), by discharging the all-solid-state battery (50) until a potential of the cathode (52) becomes lower than an elution potential of copper.
