Abstract

A device for removing ions from a solution. The device includes first and second end plates, an anion exchange membrane positioned between the first and second end plates, a first multiple of two or more first cation intercalation electrodes positioned between the first end plate and the anion exchange membrane, and one or more second intercalation electrodes positioned between the second end plate and the anion exchange membrane. The first multiple of two or more first cation intercalation electrodes and the one or more second intercalation electrodes are configured to receive an electric bias of current or voltage such that the first multiple of two or more first cation intercalation electrodes and the one or more second intercalation electrodes store and release ions from the solution.
