Document Type and Number:

Japanese Patent JP5552974

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a sulfide solid electrolyte material generating a less amount of hydrogen sulfide and capable of reducing battery resistance.SOLUTION: The sulfide solid electrolyte material contains O, and thereby crosslinking sulfur contained in the sulfide solid electrolyte material can be cut off and the generation amount of hydrogen sulfide can be reduced. Further, the sulfide solid electrolyte material contains O and F, and thereby diffusion of oxygen and metals from an electrode active material into the sulfide solid electrolyte material can be suppressed, so that battery resistance can be reduced.
