Background
For grid storage applications, there is a pressing demand for safe, low-cost, and dependable high-capacity batteries. Non-aqueous redox flow batteries (RFBs) allow for greater voltages outside of the water voltage stability window and are compatible with alkali metal anodes with ultrahigh energy density.
Redox-targeting is an approach for increasing RFB solubility that uses soluble redox-active molecules (redox mediators, RMs) to oxidize and reduce solid energy-storing materials. It is believed that by…
