摘要： The present invention is able to provide a method for producing an all-solid-state battery that has a solid electrolyte layer between a positive electrode layer and a negative electrode layer. This method for producing an all-solid-state battery is characterized by comprising: a step wherein a coating liquid is applied to at least one of the positive electrode layer and the negative electrode layer, said coating liquid containing a solid electrolyte solution, which is obtained by dissolving a solid electrolyte in a solvent, and fine particles which are insoluble in the solid electrolyte solution; and a step wherein the solvent is removed from the applied coating liquid, thereby having the solid electrolyte deposit on at least one of the positive electrode layer and the negative electrode layer.

摘要： An object of the present invention is to provide a novel sulfur-based positive electrode active material for a lithium-ion secondary battery which is excellent in cyclability and can largely improve a charging and discharging capacity, a positive electrode comprising the positive electrode active material and a lithium-ion secondary battery made using the positive electrode. The sulfur-based positive electrode active material is obtainable by subjecting a starting material comprising a polymer, sulfur and an organometallic compound dispersed in a form of fine particles to heat-treatment under a non-oxidizing atmosphere, wherein the particles of metallic sulfide resulting from sulfurization of the organometallic compound are dispersed in the heat-treated material, and particle size of the metallic sulfide particles is not less than 10 nm and less than 100 nm.
