Title:
A manufacturing method of a lithium-ion-conduction solid electrolyte
Document Type and Number:
Japanese Patent JP5999094
Kind Code:
B2
Abstract:
The present invention relates to a method of manufacturing a lithium ion conductive solid electrolyte that is used for a lithium-ion secondary battery or the like and a lithium-ion secondary battery including such a lithium ion conductive solid electrolyte. Although a method is proposed in which glass including monovalent ions whose ionic radii are larger than those of lithium ions is performed with an ion-exchange process in lithium ions contained in molten salt is proposed conventionally, the improved effect of the lithium ion conductivity was not enough. 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.
