Abstract
A regeneration method of an all-solid-state battery includes a step of preparing an all-solid-state battery having a cathode that does not contain copper, and a step of executing overdischarge control of the all-solid-state battery. 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, by discharging the all-solid-state battery until a potential of the cathode becomes lower than an elution potential of copper.
Claims7
A regeneration method of an all-solid-state battery, the regeneration method comprising:
- a step of preparing the all-solid-state battery including a cathode that does not contain copper;
- and
- a step of executing overdischarge control of the all-solid-state battery, wherein
- 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, by discharging the all-solid-state battery until a potential of the cathode becomes lower than an elution potential of copper.
An all-solid-state battery system for regenerating an all-solid-state battery including a cathode that does not contain copper, the all-solid-state battery system comprising:
- a power conversion device configured to discharge the all-solid-state battery;
- and
- a control device configured to control the power conversion device, wherein
- the control device is configured to mitigate reaction variance that is variance in electrode reaction due to charging and discharging of the all-solid-state battery, by controlling the power conversion device to discharge the all-solid-state battery until a potential of the cathode becomes lower than an elution potential of copper.
