  • Method of manufacturing high-ion conductive sulfide-based solid electrolyte using dissolution-precipitation and composition used therefor
    Patent number: 10991977
    Abstract: A method of manufacturing a high-ion conductive sulfide-based solid electrolyte using dissolution-precipitation includes preparing a composite solvent including a first solvent including a cyano group and a second solvent having a polarity index of less than 4, introducing a raw material including lithium sulfide (Li2S) and phosphorus pentasulfide (P2S5) into the composite solvent, and stirring the raw material to obtain a sulfide precipitate.
