Abstract: An organic flow battery having a positive electrode electrolyte containing organic compounds with extended conjugation and/or cyclic side chains is provided. The flow battery includes a positive electrode and a positive electrode electrolyte including first solvent and a first redox couple. The positive electrode electrolyte flows over and contacting the positive electrode. The first redox couple includes a first organic compound and a reduction product of the first organic compound. The flow battery also includes a negative electrode and a negative electrode electrolyte including a second solvent and a second redox couple. The negative electrode electrolyte flows g over and contacts the positive electrode. Typically, an ion exchange membrane is interposed between the positive electrode and the negative electrode Characteristically, the first organic compound resists crossover through the ion exchange membrane.

Abstract: A flow battery that includes an iron-based redox couple includes a positive electrode, a positive electrode electrolyte including a soluble iron-based redox couple, a negative electrode, and a negative electrode electrolyte including a cyclic organic-based redox couple. The positive electrode electrolyte flows over and contacting the positive electrode. The iron-based redox couple includes an iron-containing compound which is reduced during discharge. The negative electrode electrolyte flows over and contacting the negative electrode. The cyclic organic-based redox couple includes a cyclic organic compound. The reduction product of the cyclic organic compound being oxidized to the cyclic organic compound during discharge.
