Abstract
[Problem] To provide a method for the production of an all-solid-state battery using an alloy-based negative electrode active material in which it is possible to suppress degradation in performance of the all-solid-state battery during actual use while the restraint pressure during actual use of the all-solid-state battery is relatively small.[Solving Means] The method for producing an all-solid-state battery of the present disclosure produces an all-solid-state battery having a battery laminate comprising a positive electrode current collector layer, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode current collector layer laminated in this order, wherein the battery laminate is restrained in the lamination direction by an actual use restraint member. The negative electrode active material layer contains particles of an alloy-based negative electrode active material. The method of the present disclosure comprises the steps of, in this order, charging and discharging the battery laminate in a state in which the batter, laminate is restrained in the lamination direction by a manufacturing restr…
