Electrode design and cell operation of a capacitive deionization system

Abstract

Capacitive deionization (CDI) is a promising technology for desalination in a more energy-efficiency way than conventional techniques such as membrane separation and thermal distillation. However, a rational designed structure of the electrode materials and a proper system assembling is essentially required for achieving high CDI performance. Here, carbon electrodes are studied and tested in a deionization system which is operated at and optimized for high salt adsorption and charge efficiency. Furthermore, influence parameters of cell design are studied and evaluated.
