Abstract
The present invention provides a lithium-selective permeable membrane that can be used to recover lithium ions without performing complicated treatments on the lithium-selective permeable membrane, and that can reduce the time and cost required for recovering lithium ions. A lithium-selective permeable membrane 10 of the present invention includes a sintered body of a lithium-ion conductor. At least a part of a region of an outer surface of the lithium-selective permeable membrane 10 is composed of a surface-roughened surface 101.
Claims12
A lithium-selective permeable membrane comprising a sintered body of a lithium-ion conductor, wherein at least a part of a region of an outer surface of the lithium-selective permeable membrane is composed of a surface-roughened surface.
A method for producing a lithium-selective permeable membrane that comprises a sintered body of a lithium-ion conductor, the method comprising:
- a sintering step of sintering a molded body that comprises a lithium-ion conductor;
- and
- a surface roughening treatment step of removing a surface layer of at least a part of a region of an outer surface of the sintered body and roughening the surface after the sintering.
