Solid-state battery system and manufacturing method of regenerable solid-state secondary battery

摘要

Solid-state secondary battery system (20) which can be used in a vehicle, characterized in that it comprises: at least one solid-state secondary battery (10) which comprises a cathode-active material layer (1), an anode-active material layer (2) and a solid-state electrolyte layer (3) which is sandwiched between the cathode-active material layer (1) and the anode active material layer (2) is formed; anda deep discharge lead-through unit (11) which discharges the at least one solid-state secondary battery (10) until a state of charge of the at least one solid-state secondary battery (10) falls below 0%, wherein the deep-discharge lead-through unit (11) is an external short-circuit unit which is designed to accommodate the at least one solid-state secondary battery (10) short-circuit externally.
