Abstract
Processes for producing sulfide-based solid electrolytes include preparing a slurry by mixing a solvent with an alkali metal sulfide having a surface area greater than 6 m2/g or an alkaline earth metal sulfide having a surface area greater than 6 m2/g and a secondary sulfide. The slurry is then dried to produce the sulfide-based solid electrolyte.
Claims26
A process for producing a sulfide-based solid electrolyte comprising:
- preparing a slurry by mixing a solvent and electrolyte precursors, the electrolyte precursors comprising:
- an alkali metal sulfide having a surface area greater than 6 m2/g or an alkaline earth metal sulfide having a surface area greater than 6 m2/g, and
- a secondary sulfide;
- and
- drying the slurry to produce a sulfide-based solid electrolyte.

A process for producing a sulfide-based solid electrolyte comprising:
- preparing a slurry by mixing a solvent and electrolyte precursors, the electrolyte precursors comprising:
- an alkali metal sulfide composite, and
- a secondary sulfide;
- and
- drying the slurry to produce the sulfide-based solid electrolyte, wherein the alkali metal sulfide composite comprises a first alkali metal sulfide and a second alkali metal sulfide, wherein the second alkali metal sulfide has a D50 particle size that is at least two times greater than the D50 particle size of the first alkali metal sulfide.
