Abstract
Sustainable technology in energy-related applications will be crucial in the coming decades. As a result, developing new materials for existing processes has presently arisen as a major research priority. Recently, Deep eutectic solvents (DESs) have been expected as low-cost task-specific solvents for zinc-air batteries (ZABs). Here in, initially the various preparation methods of DESs their detection strategies, and the fundamental characteristics of DESs are summarized. Then, the recent utilization of DESs on ZABs has been reviewed. After that, the chemical and physical characteristics of DESs including phase behavior, viscosity, density, ionic conductivity, refractive index, pH, surface tension and stability have been studied. Lastly, the challenges, limitations, and possible upcoming research fields of DESs for ZABs were discussed.
