Abstract
The disclosure relates to recovering Li ions in a raw liquid into a recovery liquid at a high recovery speed. A lithium selective permeable membrane is constituted of a selective permeable membrane main body constituted of a lithium ion superconductor (ion conductor) having a particularly high ion conductivity and a Li adsorption layer formed as a thin layer on a raw liquid side (a first electrode) thereof. As a material constituting the selective permeable membrane main body, specifically, lanthanum lithium titanium oxide can be used. The Li adsorption layer is formed as a thin layer on a surface of the selective permeable membrane main body by carrying out a chemical treatment on the selective permeable membrane main body.
