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).
The invention claimed is: 1. A method for producing a sulfide all-solid-state battery, the method comprising: forming the 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 disposed between the cathode and the anode, wherein at least one of the anode active material layer and the solid electrolyte layer contains a sulfide-based solid electrolyte, initially charging the sulfide all-solid-state battery after the forming of the sulfide all-solid-state battery, and exposing a contact surface between the sulfide-based solid electrolyte and the anode active material of the sulfide all-solid-state battery to an oxygen-containing gas atmosphere at a time of the initially charging of the sulfide all-solid-state battery and optionally at a time after the initially charging of the sulfide all-solid-state battery, 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 the anode of the sulfide all-solid-state battery to 0.85 V (vs. Li/Li + ) or less. 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.
