In desalination battery technology, ions are adsorbed on both the surface and bulk of electrodes. This study reviewed capacitive deionization method evolution towards desalination battery and major parameters affecting the performance of this technology.
Here, we developed an improved approach for water desalination that increases desalination capacity compared to CDI by using two identical battery electrodes that interact only with Na +, with the channels separated by at least one anion exchange membrane, referred to as battery electrode deionization (BDI).
When a pair of electrodes is charged in capacitive deionization (CDI) systems, cations bind to the cathode and anions bind to the anode, but high applied voltages (>1.2 V) result in parasitic reactions and irreversible electrode oxidation.
Desalination batteries are a reliable and sustainable solution for the treatment of water/wastewater towards the recovery and storage of both clean water and energy.
