Capacitive Deionization Electrodes

NE_2014_07 According to a 2007 World Health Organization report, 1.1 billion people lack access to an improved drinking water supply. An upcoming method of water desalination called capacitive deionization, CDI for short, has shown promise in the removal of low salt concentrations at lower energy when contrasted to other current technologies. Upon applying a potential difference across two porous electrodes, ions are temporarily immobilized and removed, resulting in an improved water supply. Our proposed nanocomposite material hopes to achieve higher throughput which will allow CDI to become a competitive technology in water treatment.
