SULFIDE SOLID ELECTROLYTE AND METHOD FOR PRODUCING SAME, ELECTRODE MIXTURE, SOLID ELECTROLYTE LAYER, AND ALL-SOLID-STATE LITHIUM ION SECONDARY BATTERY

Document Type and Number:

WIPO Patent Application WO/2024/085045

Kind Code:

A1

Abstract:

The present invention pertains to a sulfide solid electrolyte that contains Li, P, S, and Ha, and that has an argyrodite-type crystal structure. The crystal structure has a plurality of PS4 tetrahedrons T1 in which a part of elements is optionally substituted. In the sulfide solid electrolyte, 16 elements that serve as apexes of the PS4 tetrahedrons T1 exist in a unit lattice, and the average value of the distance Δ, obtained by making said elements correspond to the S element positions at 16e sites of a PS4 tetrahedron T2 of a space group F-43m, is 0.05-0.30 Å.
