SOLID SECONDARY BATTERY SYSTEM AND MANUFACTURING METHOD OF RECOVERABLE SOLID SECONDARY BATTERY

摘要

The invention provides a solid secondary battery system including a solid secondary battery having a cathode active material layer, an anode active material layer, and a solid electrolyte layer formed between the cathode active material layer and the anode active material layer, and an overdischarge processing unit for discharging the solid secondary battery until a SOC of the solid secondary battery becomes less than 0%.
