Application progress of zinc trifluoromethanesulfonate in aqueous zinc ion batteries
With the continuous increase in global demand for clean energy, water-based zinc ion batteries have become a research hotspot in the field of energy storage due to their advantages of low cost, high safety, and environmental friendliness. In the development process of aqueous zinc ion batteries, the performance of the electrolyte plays a key role, and zinc trifluoromethanesulfonate, as an important component of the electrolyte, is gradually showing unique value and promoting technological innovation in this field.
Traditional aqueous zinc ion batteries face problems such as zinc dendrite growth and severe side reactions, which can lead to shortened battery cycle life and reduced safety. The emergence of zinc trifluoromethanesulfonate provides a new direction for solving these problems. Research has found that zinc trifluoromethanesulfonate can form a stable ionic environment in aqueous solution, and its unique anionic structure helps to inhibit the growth of zinc dendrites. The interaction between trifluoromethanesulfonate ions and zinc ions can guide the uniform deposition of zinc ions, making the surface of the zinc negative electrode smoother and effectively improving the cycling stability of the battery.
In practical applications, experimental data from numerous research teams have fully demonstrated the excellent performance of zinc trifluoromethanesulfonate. By applying an electrolyte containing zinc trifluoromethanesulfonate to aqueous zinc ion batteries, the capacity retention rate of the battery can still be maintained at a high level after multiple charge and discharge cycles, and exhibits low poLarization phenomena during the charge and discharge process, significantly improving the charge and discharge efficiency. In addition, zinc trifluoromethanesulfonate has good chemical stability and can reduce side reactions between the electrolyte and electrode materials, further extending the service life of the battery and laying a solid foundation for the application of water-based zinc ion batteries in large-scale energy storage and other fields.
