Document Type and Number:

WIPO Patent Application WO/2017/204027

Kind Code:

A1

Abstract:

Provided are: a solid electrolyte composition containing an inorganic solid electrolyte, a binder, and a dispersion medium (C) comprising the dispersion mediums (C1) and (C2) indicated below at a specific mass ratio; an electrode sheet that is for an all-solid-state secondary battery and that comprises an active material layer formed from the solid electrolyte composition, a primer layer, and a current collector; an all-solid-state secondary battery; and a method for producing the electrode sheet for an all-solid-state secondary battery and the all-solid-state secondary battery. The dispersion medium (C1) is a saturated aliphatic compound or an alicyclic compound having a boiling point of 80°C or more but less than 200°C. The dispersion medium (C2) is an aromatic compound having a boiling point of 100°C or more but less than 220°C.
