In order to enhance the desalination performance of carbon-based composite electrodes, an ion-exchange resin/carbon composite electrode was newly manufactured by mixing activated carbon powders, PTFE binder, and ion-exchange resins. The desalination performance of the electrode was greatly enhanced by about 35% due to enhancement of hydophilicity compared to that of a conductive carbon black/carbon composite electrode. It was also higher by about 14% than that of a carbon cloth electrode. The results Suggest that the desalination performance of the electrode can be improved with the introduction of ion-exchange resins, and the resulting electrode is suitable for use in capacitive deionization.
