Abstract

Inverted capacitive deionization (i-CDI) is examined using microporous SpectracarbTM carbon electrodes in 10 mmol L-1 NaCl solution without deaeration. i-CDI testing shows that using conventional operational methods, i.e., Vch = 0.8 V and Vdis = 0 V (0.8/0 V), cannot stabilize salt separation after approximately 409 hours with an averaged salt adsorption capacity (SAC) of 6.0
