Capacitive deionization with asymmetric electrodes: Electrode capacitance vs electrode surface area

Removing charged species from aqueous media is of interest in diverse applications including desalting of saline water. Capacitive deionization (CDI) devices governed by the principles of a supercapacitor use two conductive electrodes which are preferably nanostructured to provide large surface area for adsorption of ions. Practical capacitive deionization systems operate at very low voltages, lower …
