S. Guiheneuf, T. Godet-Bar, J.-M. Fontmorin, C. Jourdin, D. Floner, F. Geneste. A new hydroxyanthraquinone derivative with a low and reversible capacity fading process as negolyte in alkaline aqueous redox flow batteries.
Aqueous redox flow batteries (ARFBs) based on the electrolyte solutions of redox-active organic molecules are very attractive for the application of large-scale electrochemical energy storage.
We further show that this O- alkylated anthraquinone can be used in a flow battery at pH 12 with an inexpensive hydrocarbon-based membrane that features exceptionally high permselectivity and low permeability of both the alkylated anthraquinone and ferricyanide species, affording century-scale timescales for reactant crossover.
This result adds the important attribute of long calendar life to quinone-based RFBs. We demonstrate a long-lifetime, aqueous redox-flow battery that can operate at a pH as low as 12 while maintaining an open-circuit voltage of over 1 V. We functionalized 2,6-dihydroxyanthraquinone (2,6-DHAQ) with highly alkali-soluble carboxylate terminal groups.
The 2,3-HCNQ molecule exhibits high solubility and can carry out a reversible two-electron redox process with rapid redox kinetics. The assembled 2,3-HCNQ/K 4 Fe (CN) 6 ARFB delivered a cell voltage of 1.02 V and realized a peak power density of 0.255 W cm –2.
