Ionic cyclic nitroxyl radical oligomers, methods of making the ionic cyclic nitroxyl radical oligomers, and electrochemical cells, such as aqueous organic redox flow batteries (AORFBs) that use the ionic nitroxyl radical oligomers as catholytes are provided. The oligomers are larger than individual cyclic nitroxyl radical molecules, but maintain a high density nitroxyl radical groups within the molecule. As a result, when the oligomers are used as catholytes in an AORFB, they are able to reduce catholyte permeation through the ion-conducting membrane, while providing a high volumetric capacity and cycling stability.
