Claims12
A method for producing a mixture of an alkali metal halide and an alkali metal sulfide, comprising causing a reaction of an alkali metal sulfide and a substance of the following formula (1) in a solvent excluding water in order to produce the alkali metal halide in mixture with an excess of alkali metal sulfide that remains unreacted and wherein the amount of the excess of alkali metal sulfide that remains unreacted in the mixture is from 4 to 8 times based on molar ratio of the substance represented by the formula (1):
- X2 (1)
- wherein X represents a halogen element.
A method for producing a sulfide-based solid electrolyte, comprising producing a sulfide-based solid electrolyte using a mixture of alkali metal halide and alkali metal sulfide produced by causing a reaction of an alkali metal sulfide and a substance of the following formula (1) in a solvent excluding water in order to produce the alkali metal halide in mixture with an excess of alkali metal sulfide that remains unreacted and wherein the amount of the excess of alkali metal sulfide that remains unreacted in the mixture is from 4 to 8 times based on molar ratio of the substance represented by the formula (1):
- X2 (1)
- wherein X represents a halogen element.
