The present invention provides a redox flow battery comprising a negative electrode (also referred to herein as an “anode”) immersed in a first liquid electrolyte (also referred to herein as a “negative electrolyte” or “anolyte”), a positive electrode (also referred to herein as a “cathode”) immersed in a second liquid electrolyte (also referred to herein as a “positive electrolyte” or “catholyte”), and a cation-permeable separator (e.g., a membrane or other cation-permeable material) partitioning the negative electrode/anolyte from the positive electrode/catholyte. The redox reactant of the catholyte comprises a compound of Formula (I) as described herein.
