Document Type and Number:
WIPO Patent Application WO/2019/087752
Kind Code:
A1
Abstract:
Provided is a solid electrolyte composition which is not only capable of imparting a solid electrolyte layer and/or an electrode active material layer constituting a solid electrolyte-containing sheet with excellent mechanical strength by being used as a layer-constituting material for the solid electrolyte-containing sheet, but also capable of imparting the solid electrolyte-containing sheet with high ion conductivity. This solid electrolyte composition contains (A) an inorganic solid electrolyte that has conductivity of ions of a metal in group 1 or group 2 of the periodic table, (B) a binder, (C) a dispersion medium and (D) a solvent which comprises a fluorine atom, an oxygen atom, a nitrogen atom or a chlorine atom in the chemical structure; and a polymer that constitutes the binder (B) has a partial structure containing an acyclic siloxane structure represented by general formula (I) and a partial structure represented by general formula (II). A solid electrolyte-containing sheet according to the present invention has a layer that is configured from this solid electrolyte composition. An all-solid-state secondary battery according to the present invention contains this solid electrolyte-containing sheet. A method for producing a solid electrolyte-containing sheet and a method for producing an all-solid-state secondary battery according to the present invention comprise a step for applying this solid electrolyte composition onto a substrate.
