Title:
SULFIDE SOLID ELECTROLYTE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/075618
Kind Code:
A1
Abstract:
Provided is a sulfide solid electrolyte manufacturing method comprising a first step for mixing a raw-material-containing substance containing lithium atoms, phosphorus atoms, sulfur atoms, and halogen atoms in an organic solvent to obtain a mixture, a second step for radiating a microwave of 0.5 to 700 W/g onto the mixture to heat the mixture to 50-360°C, and a third step for cooling the mixture to 20-70°C, wherein the second and third steps are repeated two to 50 times. According to this method, it is possible to employ a liquid phase method, to reduce the heating temperature, to suppress granulation caused by heating so that a particle size is maintained, and to be capable of efficiently manufacturing sulfide solid electrolytes having an higher quality.
