Title:
METAL ION RECOVERY DEVICE AND METAL ION RECOVERY METHOD
Document Type and Number:
WIPO Patent Application WO/2015/020121
Kind Code:
A1
Abstract:
The present invention selectively and inexpensively recovers liquid-borne metal ions. This metal ion recovery device (1) uses a selective transmission membrane (10) that selectively allows the transmission of Li, and mesh-form negative electrodes (11) and positive electrodes (12) are formed on both primary surfaces of the selective transmission membrane (10), which assumes the form of a flat plate. This structure is provided in a treatment tank (8), and a stock solution (100) containing Li ions (50) and a recovery solution (200) that acts as a recovery destination are partitioned by the selective transmission membrane (10) inside the treatment tank (8). Lithium nitride (Li3N), Li10GeP2S12, (Lax, Liy)TiOz, Li1+x+y Alx(Ti, Ge)2-x SiyP3-yO12, etc., which are super lithium ion conductors, can be used for the selective transmission membrane (10).
