Title:
SOLID ELECTROLYTE SHEET AND METHOD FOR PRODUCING NEGATIVE ELECTRODE SHEET FOR ALL-SOLID-STATE SECONDARY BATTERY AND ALL-SOLID-STATE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/189822
Kind Code:
A1
Abstract:
Provided is a method for producing a solid electrolyte sheet in which: a pre-molded body obtained by subjecting inorganic solid electrolyte particles containing solid particles that plastically deform at 250°C or less to preliminary pressure molding at a specific temperature is heated to a specific temperature, or inorganic solid electrolyte particles containing solid particles that have a thermal decomposition temperature of 250°C or less and that plastically deform at 250°C or less are heated to a specific temperature; the result is then subjected to pressure molding at a specific temperature; and a solid electrolyte layer comprising inorganic solid electrolyte particles is formed. Also provided is a method for producing a negative electrode sheet for an all-solid-state secondary battery and an all-solid-state secondary battery, said method including the aforementioned method for producing a solid electrolyte sheet.
