Organic Eutectic Electrolytes for Future Flow Batteries

In this issue of Chem, Yu and coworkers report phthalimide-based eutectic anolytes, which achieved a high concentration and enhanced redox reversibility. The organic-molecule-based eutectic electrolytes take advantages of both the superior tunability of the organic molecule and the high molar concentration of the redox-active molecules of the eutectic solvents. With combined computational and experimental analysis, this work demonstrates that forming eutectic electrolytes with self-containing redox-active organics is a promising strategy for the future development of high-energy-density redox-flow batteries.
