The solid electrolyte composition contains an inorganic solid electrolyte having conductivity of ions of metals belonging to Group 1 or Group 2, and a compound of general expression (1). In the expression, R1 is an m+n-valent linking group, R2 and R3 are single bonds or divalent linking groups, A1 is a monovalent group including one or more groups selected from an acidic group, a group having a basic nitrogen atom, a (meth)acryloyl group, (meth)acrylamide group, an alkoxysilyl group, an epoxy group, an oxetanyl group, an NCO group, an SN group, an SH group and an OH group, P1 is a group that includes a C8 or higher hydrocarbon group, m represents 1-8, n represents 1-9, and m+n is between 3 and 10.

Description

technical field [0001] One embodiment of the present invention relates to a solid electrolyte composition, an electrode sheet for a battery and a manufacturing method thereof, and an all-solid secondary battery and a manufacturing method thereof. Background technique [0002] Lithium-ion batteries that are lightweight and have high energy density are used as medium-sized or large-sized batteries used in electric vehicles, household batteries, and the like. Lithium-ion batteries use an organic electrolytic solution as an electrolyte, so there is a risk of leakage or fire. In recent years, from the viewpoint of improving safety and reliability, research on all-solid-state secondary batteries in which the electrolyte is replaced by a non-combustible inorganic solid electrolyte has been conducted. The inorganic solid electrolyte has a sulfide-based inorganic solid electrolyte and an oxide-based inorganic solid electrolyte. The sulfide-based inorganic solid electrolyte can achie...
