Abstract
An apparatus for removal of ions from water having: a carbon coated first current collector; a second current collector; a spacer in between the first and second current collectors to allow water to flow in between the first and second current collectors; a first charge barrier in between the first carbon coated current collector and the spacer to selectively allow anions or cations to flow through the first charge barrier. The apparatus may have a second charge barrier coated on the carbon coated first current collector and in contact with the first charge barrier to improve contact. A third charge barrier functioning as a membrane may be provided in between the second current collector and the spacer.
