ELECTROLYZER

Abstract:

The present disclosure is intended to provide an electrolyzer capable of selectively recovering lithium. The electrolyzer recovers lithium ions Li.sup.+ from a material M. The electrolyzer includes: a pair of electrodes; and a cation exchange membrane provided between the pair of electrodes and having a lithium ion conductivity. The cation exchange membrane allows, among cations contained in the material M, more lithium ions Li.sup.+ to pass therethrough than other cations Ca.sup.2+ and Na.sup.+. The electrolyzer is configured to apply a voltage between the pair of electrodes.
