“…The unbalanced adsorption and desorption of ions during the discharging and charging half cycles can be seen in Figure a–c (i.e., first to 10th, 31st to 40th, and 41st to 50th cycles, respectively). This can be attributed to (1) the incomplete desorption of ions previously captured in the electrode, resulting in an unbalanced adsorption and desorption of ions and (2) the dissolution of the active material (i.e., VO x NPs) . As a result, a decrease in the SAC value and poor stability can be observed during the cyclic test, suggesting a necessity to prevent the electrode material from dissolution in order to enhance the cyclic performance of ECDI cells.…”

“…Through the hybridization of carbon-based electrode materials with metal oxides (e.g., manganese dioxide/activated carbon composites, ,,, titanium oxide/activated carbon composites), , significant improvement in deionization capabilities is achievable because of the creation of highly reversible redox reactions in the carbon nanostructure. Accordingly, electrochemical deionization (ECDI), an innovative deionization technology utilizing the CDI and/or Faradaic desalination materials to construct the desalination cell in the symmetric, asymmetric, or hybrid designs, is established with unique advantages of high salt removal capacity and energy efficiency. , …”

“…When the charging is suddenly shut done, both the conductivity and voltage drop slowly due to the "memory effect" of the redox active electrodes. [50,51] The mechanism of AC || CMO-MS-600 CDI device is explored by performing the in-situ XRD. Prior to the in-situ XRD experiment, a customized battery was fabricated where the CMO-MS-600 and AC is employed as the positive electrode and negative electrode, respectively.…”
