METHOD FOR MANUFACTURING ALL-SOLID-STATE BATTERY AND ALL-SOLID-STATE BATTERY MANUFACTURED THEREBY

The present invention relates to a method of manufacturing an all-solid-state battery, comprising: (1) manufacturing an all-solid-state battery by stacking a positive electrode current collector, a positive electrode layer, a solid electrolyte layer, a negative electrode layer, and a first negative electrode current collector in a sequence; (2) charging and discharging the manufactured all-solid-state battery; (3) peeling off and removing the first negative electrode current collector from the all-solid-state battery in a discharged state; and (4) disposing a second negative electrode current collector in contact with the negative electrode layer; and an all-solid-state battery manufactured by the above method.
