  • METHOD OF PROVIDING A CHARGE BARRIER FLOW-THROUGH CAPACITOR SYSTEM
    Publication number: 20140346043
    Abstract: Flow-through capacitors are provided with one or more charge barrier layers. Ions trapped in the pore volume of flow-through capacitors cause inefficiencies as these ions are expelled during the charge cycle into the purification path. A charge barrier layer holds these pore volume ions to one side of a desired flow stream, thereby increasing the efficiency with which the flow-through capacitor purifies or concentrates ions.
    Type: Application
