a Specific adsorption capacity vs. time during the first 4 cycles (1.2 V, 1000 mg L−1 NaCl solution), b specific adsorption capacity at different voltages (1000 mg L−1 NaCl solution), and c the corresponding Kim-Yoon plots. d Wind rose of SAC comparison with reported state-of-the-art CDI electrodes at 1.2 V and high voltages. e Cycleability of O/D NSLC-800 electrodes (1.6 V, 1000 mg L−1 NaCl solution). f Schematic illustration of capacitive deionization system with multi-channel tandem. Concentration of different salt ions before and after treatment of g brackish water and h actual circulating cooling water at a cell voltage of 1.6 V. Error bars in (b) represent the standard deviation and were calculated on the basis of three experimental data points.
