SOLID ELECTROLYTE COMPOSITION, ALL-SOLID SECONDARY BATTERY SHEET, ALL-SOLID SECONDARY BATTERY, AND METHOD OF MANUFACTURING ALL-SOLID SECONDARY BATTERY SHEET OR ALL-SOLID SECONDARY BATTERY

摘要

Provided are: a solid electrolyte composition comprising an inorganic solid electrolyte conductive to ions of a metal of Group I or Group II of the periodic table, a binder, and a disperse medium, wherein the binder comprises a polymer which contains a constituent component expressed by the general formula (1), and a constituent component derived from a macromonomer having a number average molecular weight of not less than 2,000; an all-solid secondary battery sheet and an all-solid secondary battery using the composition; and a method of manufacturing each of the all-solid secondary battery sheet and the all-solid secondary battery. In the formula, α represents a ring; L represents -O-, -NR⁴-, or -S-; R¹ to R⁴ represents a hydrogen atom or a monovalent substitution group; and * represents a binding portion of the constituent components.
