Aqueous organic redox flow batteries (AORFBs) are a promising grid-scale energy storage technology, but the development of high-performance catholytes has been challenging. Here the researchers reveal redox-active species based on dimers of (2,2,6,6-tetramethylpiperidin-1-yl)oxyl that demonstrate high cycling stability, power and volumetric capacity in AORFBs.
