Document Type and Number:
WIPO Patent Application WO/2021/014852
Kind Code:
A1
Abstract:
The present invention provides: an inorganic solid electrolyte-containing composition which has excellent initial dispersibility and excellent dispersion stability; a sheet for all-solid-state secondary batteries, an electrode sheet for all-solid-state secondary batteries, and an all-solid-state secondary battery, each of which uses this inorganic solid electrolyte-containing composition; a method for producing a sheet for all-solid-state secondary batteries; and a method for producing an all-solid-state secondary battery. An inorganic solid electrolyte-containing composition which contains an inorganic solid electrolyte, a binder and an organic solvent, wherein: at least two binders having different adsorption rates with respect to the inorganic solid electrolyte, namely a binder A and a binder B are contained as the binder; the binder A has an adsorption rate of 15% or more; and the binder B has an adsorption rate of less than 10%. A sheet for all-solid-state secondary batteries, an electrode sheet for all-solid-state secondary batteries, and an all-solid-state secondary battery, each of which uses this inorganic solid electrolyte-containing composition; and a method for producing a sheet for all-solid-state secondary batteries and a method for producing an all-solid-state secondary battery, each method using this inorganic solid electrolyte-containing composition.
