Solid electrolyte composition, solid electrolyte-containing sheet, electrode sheet for all-solid secondary battery and all-solid secondary battery, and method for manufacturing solid electrolyte-containing sheet and all-solid secondary battery

摘要

Even if it is bent with a small bending radius, it is difficult to generate defects in the layer, and even after such bending, a solid electrolyte composition capable of forming a layer showing excellent ionic conductivity, a solid electrolyte-containing sheet using the same, an electrode sheet for an all-solid secondary battery, and An all-solid-state secondary battery, and a method for manufacturing the same are provided. The periodic table includes inorganic solid electrolytes (A), binders (B), and dispersion media (C) having conductivity of ions of metals belonging to Group 1 or 2, The binder (B) includes a first binder (B1) that precipitates and a second binder (B2) that does not precipitate, when subjected to centrifugal separation treatment under specific conditions in the dispersion medium (C), A solid electrolyte composition in which the content X of the first binder (B1) and the content Y of the second binder (B2) satisfy the following formula, a solid electrolyte-containing sheet using the solid electrolyte composition, an electrode sheet for an all-solid-state secondary battery and an all-solid secondary Batteries, and methods of manufacturing them. 0.10≤Y / (X + Y) ≤0.80
