Document Type and Number:

WIPO Patent Application WO/2022/070850

Kind Code:

A1

Abstract:

Provided are: an inorganic solid-state electrolyte-containing composition having excellent dispersion properties, coating suitability and cycle properties; a sheet for an all-solid-state secondary battery and an all-solid-state secondary battery, each of which uses the inorganic solid-state electrolyte-containing composition; a method for producing a sheet for an all-solid-state secondary battery; and a method for producing an all-solid-state secondary battery. This inorganic solid-state electrolyte-containing composition to be used in an all-solid-state secondary battery contains an inorganic solid-state electrolyte, a polymer binder and a dispersant, exhibits a pickup rate of the inorganic solid-state electrolyte by the polymer binder of 50% or less, and satisfies a specific surface energy relationship between the inorganic solid-state electrolyte and the polymer binder.
