WIPO Patent Application WO/2019/017309

A1

A solid electrolyte composition, a solid electrolyte-containing sheet and an all-solid-state secondary battery that are obtained using this solid electrolyte composition, and a production method for the solid electrolyte-containing sheet and the all-solid-state secondary battery, said solid electrolyte composition containing: a polymer (A) having a mass average molecular weight of at least 5,000; a compound (B) having at least two polymerization reactive groups and having a molecular weight ratio to the number of these polymerization reactive groups of no more than 230; and an electrolyte salt (C) having a metal ion belonging to the first or second group on the periodic table. The mass ratio of the compound (B) in a component having a boiling point of at least 210°C in the solid electrolyte composition is at least 10%.
