Description

Ion exchange membranes have been used in various industrial fields for desalination and concentration applications. Also, by using a bipolar membrane, it is possible to produce acids and alkalis from several salts. In recent years, such a bipolar electrodialysis method, that can reduce the volume of waste has been attracting attention even in the recovery of lithium, which is a material of a secondary battery. In this report, we will introduce our efforts to produce lithium hydroxide from lithium sulfate or lithium carbonate.
