Composition containing sulfide-based solid electrolyte, method of storing sulfide-based solid electrolyte in the atmosphere, and method of regenerating sulfide-based solid electrolyte

摘要

PROBLEM TO BE SOLVED: To provide a composition containing a sulfide-based solid electrolyte capable of satisfactorily suppressing deterioration in the atmosphere regardless of the composition of the sulfide-based solid electrolyte. SOLUTION: The sulfide-based solid electrolyte has a water-impermeable matrix existing around the sulfide-based solid electrolyte, and the water-impermeable matrix does not show reactivity with the sulfide-based solid electrolyte. A composition containing a sulfide-based solid electrolyte that has a double bond or a triple bond and does not show reactivity with a sulfide-based solid electrolyte, and is soluble in a hydrocarbon-based solvent.
