“…Moreover, the surface area of the electrode (0.07 cm 2 ) used in our system is much smaller than the other reported systems (e.g., 2 cm 2 in Ag/NMO cell and 2.8 cm × 2.8 cm in BiOCl/NMO). Table S1, Supporting Information, shows the removal of surface coverage‐dependent Cl − ions from the sea water.…”

“…Recently, a new desalination technique has been developed based on the electrochemical reaction occurring in the bulk electrode materials, and this is known as a reversible desalination battery. In this process, ions are removed from the salted sea water by faradaic reactions where ions are inserted into the electrode materials by applying constant current (charging process) and the inserted ions are recovered in a separate solution by a discharge process where the energy applied could be reconsumed (partially or fully) as electrical energy . A cell consisting NaMnO 2 and Ag was demonstrated by Pasta et al for the first time, where Na was inserted into MnO 2 , and Cl − was stored as AgCl in the Ag electrode .…”

“…The Cl − ions can be mostly removed from the sea water by 1) the oxidation of Cl − ion into Cl 2 gas, which is highly toxic in nature and needs a high electrode potential of +1.36 V (higher than O 2 evolution; +1.23 V); 2) a membrane separation process, including RO, deionization, etc. ; and 3) an energy storage device such as a capacitive deionization and desalination battery . Except the last one, all others are energy feeding processes.…”

Desalination battery is an emerging concept used in electrochemical technology to solve the problems in sea water desalination. However, identifying an efficient and reversible chloride (Cl−) storage electrode is a major challenge for the development of desalination batteries. A new membraneless, reversible desalination battery consisting of an efficient, reversible, high‐capacity Cl− storage electrode, ferrocyanide molecule immobilized polysilsesquioxane (redox‐PSQ), in combination with the cation storage material, a nickel hexacyanoferrate film in real sea water, is described. The redox‐PSQ polymer is superior over the other reported Cl− storage electrodes (Ag and Bi electrodes) in terms of cost, stability, reversibility, and Cl− ion removal capacity in real‐time applications. About 164 mg L−1 of Cl− ion is removed from natural sea water per 7.6 × 10−8 mol cm−2 surface concentration of electrode material with 98% coulombic efficiency. During the desalination process, alkali ions move toward nickel hexacyanoferrate and Cl− ions moves toward the redox‐PSQ film from the sea water. During the salination process, the stored ions are recovered from the electrode surface as a result of partial energy recovery. Furthermore, this electrode also removes the sulfate ion present in the sea water by the electrostatic adsorption phenomenon. In addition, a high‐voltage (2.3 V), Mg//redox‐PSQ polymer cell is constructed with a red light‐emitting diode that glows during the salination process.

The family of 2D transition metal carbides, nitrides, and carbonitrides (collectively called MXenes) is rapidly studied since the initial synthesis of Ti3C2Tx (MXene). The surface of MXenes etched by hydrofluoric acid has hydrophilic groups (F, OH, and O), which leads the surface to be negatively charged. Consequently, the negatively charged surface can facilitate the compounding of MXenes with other positively charged materials and prevent MXenes from aggregating with some negatively charged substances, thus promoting the formation of a stable dispersion. The MXene‐based composites have better electrochemical performance than both precursors due to synergistic effects. This review elaborates and discusses the development of MXene‐based composites. It is aimed to summarize the various methods of fabricating MXene‐based composites. The applications of MXene‐based composites in batteries and supercapacitors are presented along with analysis of their excellent electrochemical performances. Finally, the authors propose the approach for further enhancing the electrochemical performances of MXene‐based composite electrode materials.

Polypyrrole as a Novel Chloride‐Storage Electrode for Seawater Desalination

et al. 2019

View full text Add to dashboard Cite

The desalination battery is regarded as a promising high‐efficiency technology for seawater desalination on account of the reversible salt‐ion storage in the bulk of the battery electrodes. Herein, polypyrrole is used as a new electrode to store chloride ions in seawater desalination. The as‐prepared polypyrrole composite electrode shows good electrochemical reversibility in chloride‐ion storage and removal in the aqueous NaCl electrolyte. When this chloride electrode is incorporated with a sodium electrode of sodium manganese oxide, a desalination battery that can capture chloride and sodium ions from the electrolyte through the electrochemical redox reactions is obtained. A stable and reversible capacity of 40 mAh g−1 of the desalination battery is achieved after 200 cycles.
