SOLID ELECTROLYTE AND ALL-SOLID-STATE BATTERY COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2024/043740

Kind Code:

A1

Abstract:

The objective of the present invention is to improve the air stability of a conventional sulfide-based solid electrolyte. The present invention relates to: a solid electrolyte having an argyrodite-type crystal structure doped with a cation in which the ratio (r/rs) of the ionic radius (r) (unit: Å) of the cation to the ionic radius ((rs) (unit: Å) of a S2- ion is 0.20-0.30; and an all-solid-state battery comprising same.
