Title:
ELECTROLYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/074426
Kind Code:
A1
Abstract:
Provided is an electrolysis device capable of collecting lithium from seawater, brackish water, recycled effluent, and the like that contain lithium ions, and capable of generating a carbon compound from carbon dioxide. The electrolysis device comprises a first electrode part, a second electrode part, a lithium ion exchanging part, a first electrolytic solution, a second electrolytic solution that contains lithium ions, and a first gas supply part capable of supplying a first carbon gas including carbon dioxide. The first electrode part includes a catalyst layer. The catalyst layer is in contact with the first electrolytic solution. The second electrode part faces the first electrode part with the lithium ion exchanging part therebetween and is in contact with the second electrolytic solution. The lithium ion exchanging part is provided so as to separate the first electrolytic solution from the second electrolytic solution, and selectively allows passage of lithium ions from the second electrolytic solution to the first electrolytic solution. The electrolytic device is configured to, by applying voltage between the first electrode part and the second electrode part while supplying the first carbon gas from the first gas supplying part to the first electrode part, reduce carbon dioxide in the first carbon gas and generate a carbon compound different from carbon dioxide.
