  • Method of manufacturing lithium ion conductive solid electrolyte and lithium-ion secondary battery
    Patent number: 9748601
    Abstract: A method of manufacturing a lithium ion conductive solid electrolyte includes (a) a step of preparing an object to be processed including a crystalline material, that includes alkali metal other than lithium and whose ionic conductivity at room temperature is greater than or equal to 1×10?13 S/cm; and (b) a step of performing an ion-exchange process on the object to be processed in molten salt including lithium ions.
    Type: Grant
