It is possible to reduce the deterioration of the battery performance even when the charge / discharge cycle is repeated, to prevent the generation of toxic gas when the battery is broken, to prevent the generation of all-solid lithium sulfur A battery and a manufacturing method thereof are provided. By using a positive electrode containing sulfur and a conductive material, a negative electrode containing lithium metal, and an oxide-based solid electrolyte as an electrolyte layer interposed therebetween, all-solid lithium sulfur batteries with high performance and little deterioration in performance are obtained. A positive electrode slurry containing sulfur is coated on the positive electrode side of the oxide-based solid electrolyte formed body and dried to form a positive electrode, and the oxide-based solid electrolyte formed body is placed on the lithium foil serving as a negative electrode to closely adhere the lithium foil. Thereby, the battery cell having the structure in which the oxide-based solid electrolyte is interposed between the positive electrode and the negative electrode can be efficiently assembled. |
