Enhanced capacitive deionization of an integrated membrane electrode by thin layer spray-coating of ion exchange polymers on activated carbon electrode

Capacitive deionization (CDI) has emerged as a novel desalination technology due to its cleanliness and low energy consumption. Despite being based on the principle of an electric double layer for ion adsorption on porous carbon materials, the inevitable faradaic reaction and the existence of co-ion repulsion reduce the charge efficiency (CE), leading to a low salt adsorption capacity (SAC). Herein, an integrated membrane electrode (IME),...
