Abstract
A method for producing a solid electrolyte including step of bringing the following into contact with each other in a solvent having a solubility parameter of 9.0 or more: an alkali metal sulfide; one or two or more sulfur compounds selected from phosphorus sulfide, germanium sulfide, silicon sulfide and boron sulfide; and a halogen compound.
Claims23
A method for producing a solid electrolyte, comprising contacting the following (i), (ii) and (iii) with each other in a solvent having a solubility parameter of 9.0 or more without using a mixing and grinding apparatus:
- (i) an alkali metal sulfide;
- (ii) one or more sulfur compounds selected from the group consisting of phosphorus sulfide, germanium sulfide, silicon sulfide and boron sulfide;
- and
- (iii) a halogen compound.
A method for producing a solid electrolyte, comprising contacting the following (i), (ii) and (iii) with each other in tetrahydrofuran without using a mixing and grinding apparatus:
- (i) an alkali metal sulfide;
- (ii) one or more sulfur compounds selected from the group consisting of phosphorus sulfide, germanium sulfide, silicon sulfide and boron sulfide;
- and
- (iii) a halogen compound.
A method for producing a solid electrolyte, comprising contacting the following (i), (ii) and (iii) with each other in an ether of the formula R1—O—R2 where R1 and R2 are independently C1-C6 alkyl groups without using a mixing and grinding apparatus:
- (i) an alkali metal sulfide;
- (ii) one or more sulfur compounds selected from the group consisting of phosphorus sulfide, germanium sulfide, silicon sulfide and boron sulfide;
- and
- (iii) a halogen compound.
