METHOD OF PRODUCING SOLID ELECTROLYTE-CONTAINING SHEET, METHOD OF PRODUCING ELECTRODE SHEET FOR ALL-SOLID SECONDARY BATTERY, AND METHOD OF MANUFACTURING ALL-SOLID SECONDARY BATTERY

Japanese Patent JP2018120739

A

PROBLEM TO BE SOLVED: To provide a method of producing a solid electrolyte-containing sheet for use in an all-solid secondary battery, in which a decrease in ion conductivity of an all-solid secondary battery can be effectively suppressed and also a short circuit during battery operation can be suppressed, a method of producing an electrode sheet for an all-solid secondary battery, and a method of manufacturing an all-solid secondary battery.SOLUTION: A method of producing a solid electrolyte-containing sheet, a method of producing an electrode sheet for an all-solid secondary battery, and a method of manufacturing an all-solid secondary battery include the steps of dry-mixing a sulfide-based inorganic solid electrolyte and hydrophobic fumed silica, and performing dry deposition of a mixture obtained through the previous step, the ratio of the hydrophobic fumed silica in the mixture being 0.2-2.0 mass%.SELECTED DRAWING: Figure 1
