Abstract:

Sodium chloride (NaCl), as a typical ionic compound, exhibits high ionic conductivity after dissolution or melting. It has a high solubility in water, glycerin, and other solvents, and is cheap and readily available. With these important physicochemical characteristics, it has been increasingly favored by researchers. Therefore, this paper reviews the recent progress made in the regulation of electrode materials using NaCl. The preparation of novel electrode materials via a NaCl-based template method and NaCl-based molten salt method is emphasized. The regulation mechanism of NaCl on the microstructure and morphology of electrode materials and the characteristics and advantages of freeze-drying, sol-gel, single molten salt, and mixed molten salt methods are analyzed in detail. Finally, the challenges faced with the related technologies towards industrial application are highlighted, and the future development is forecasted.

Key words: NaCl, template method, molten salt method, electrode materials, supercapacitors
