Abstract

Official abstract text for this publication.

A method for producing a sulfide all-solid-state battery with a high capacity retention rate, and a sulfide all-solid-state battery with a high capacity retention rate. The method for producing a sulfide all-solid-state battery may comprise forming a sulfide all-solid-state battery, initially charging the sulfide all-solid-state battery after the forming of the sulfide all-solid-state battery, and exposing the sulfide all-solid-state battery to an oxygen-containing gas atmosphere at at least any one of a time of the initially charging of the sulfide all-solid-state battery and a time after the initially charging of the sulfide all-solid-state battery.

First claim

Opening claim text (preview).

1 . A method for producing a sulfide all-solid-state battery, the method comprising: forming a sulfide all-solid-state battery, initially charging the sulfide all-solid-state battery after the forming of the sulfide all-solid-state battery, and exposing the sulfide all-solid-state battery to an oxygen-containing gas atmosphere at at least any one of a time of the initially charging of the sulfide all-solid-state battery and a time after the initially charging of the sulfide all-solid-state battery. 2 . The method for producing the sulfide all-solid-state battery according to claim 1 , wherein, in the initially charging of the sulfide all-solid-state battery, the sulfide all-solid-state battery is initially charged in the oxygen-containing gas atmosphere, and after the initially charging of the sulfide all-solid-state battery, the sulfide all-solid-state battery is exposed to the oxygen-containing gas atmosphere. 3 . The method for producing the sulfide all-solid-state battery according to claim 1 , wherein, in the initially charging of the sulfide all-solid-state battery, the sulfide all-solid-state battery is initially charged in the oxygen-containing gas atmosphere to set a potential of an anode of the sulfide all-solid-state battery to 0.85 V (vs. Li/Li + ) or less. 4 . A sulfide all-solid-state battery comprising: a cathode comprising a cathode active material layer that contains a cathode active material, an anode comprising an anode active material layer that contains an anode active material, and a solid electrolyte layer being disposed between the cathode and the anode and containing a solid electrolyte, wherein at least any one of the anode active material layer and the solid electrolyte layer contains a sulfide-based solid electrolyte, and the sulfide-based solid electrolyte comprises a high oxygen concentration layer on a surface in contact with the anode active material, the high oxygen concentration layer having a higher oxygen concentration than other parts except the contact surface.
