AI Technical Summary
Technical Problem
Existing technologies for manufacturing sulfide-based solid electrolytes often result in the incomplete dissolution of raw materials, leading to the presence of impurities that affect ionic conductivity. Furthermore, traditional methods are cumbersome and difficult to mass-produce.
Method used
Sulfide-based solid electrolytes are prepared by mixing raw materials in an organic solvent, performing heating, cooling and reheating steps, heat treatment at high temperature, combined with stirring and drying, and suppressing the generation of impurities.
Benefits of technology
The manufacturing of sulfide-based solid electrolytes with high ionic conductivity and virtually no impurities has been achieved, simplifying the process and improving production efficiency.
