Abstract: Ionic conductive chromophores can be used as the positive electrolytes for high-energy density, nonaqueous redox flow battery (NRFB) systems. The nonaqueous nature of the NRFB systems allow for high operation voltage (compared to aqueous systems). Furthermore, the structure modifications to chromophores described herein improve the solubility of the resultant ionic conductive chromophores, thereby allowing them to be used in flow cell configurations.
