Abstract

Flow-through capacitors (15) are provided with one or more charge barrier layers (3). Ions trapped in the pore volume of flow-through capacitors (15) cause inefficiencies as these ions are expelled during the charge cycle into the purification path. A charge barrier layer (3) holds these pore volume ions to one side of a desired flow stream, thereby increasing the efficiency with which the flow-through capacitor (15) purifies or concentrates ions.
