Kind Code:

B2

Abstract:

Provided are an inorganic solid electrolyte-containing composition that contains a sulfide-based inorganic solid electrolyte (SEA) of average particle diameter 1 µm or greater, a polymer binder (BA) for which the adsorption rate with respect to a solid electrolyte (SEA) is 30% or greater, a sulfide-based inorganic solid electrolyte (SEB) for which the average particle diameter is less than 1 µm, and a polymer binder (BB) for which the adsorption rate with respect to an inorganic solid electrolyte (SEB) is less than 30%, a sheet for an all-solid-state secondary battery and an all-solid-state secondary battery that use this inorganic solid electrolyte-containing composition, and the method for manufacturing these.
