INORGANIC-SOLID-ELECTROLYTE-CONTAINING COMPOSITION, SHEET FOR ALL-SOLID-STATE SECONDARY BATTERY, ALL-SOLID-STATE SECONDARY BATTERY, AND METHODS FOR MANUFACTURING SHEET FOR ALL-SOLID-STATE SECONDARY BATTERY AND ALL-SOLID-STATE SECONDARY BATTERY

WIPO Patent Application WO/2021/157278

A1

Provided are: an inorganic-solid-electrolyte-containing composition that has exceptional dispersion stability and handling performance, and makes it possible to realize a low resistance structural layer by suppressing any rise in interface resistance between solid particles; a sheet for all-solid-state secondary batteries and an all-solid-state secondary battery, in each of which the inorganic-solid-electrolyte-containing composition is used; and methods for manufacturing a sheet for all-solid-state secondary batteries and an all-solid-state secondary battery. The inorganic-solid-electrolyte-containing composition for all-solid-state secondary batteries contains an inorganic solid electrolyte, a polymer binder, a metal-element-containing compound, and a dispersion medium, wherein the metal-element-containing compound can supply a polymer that forms a polymer binder by using the metal elements constituting the molecules as ions, the polymer binder is dissolved in the dispersion medium, and the metal-element-containing compound is present in a solid state.
