   Abstract:
   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 propose a high-performance ARFB system utilizing 2-hydroxy-3-carboxy-1,4-naphthoquinone (2,3-HCNQ) and K4Fe(CN)6 as the anolyte and catholyte active species, respectively. 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/K4Fe(CN)6 ARFB delivered a cell voltage of 1.02 V and realized a peak power density of 0.255 W cm^-2. The 2,3-HCNQ/K4Fe(CN)6 ARFB can be stably operated at a current density of 100 mA cm^-2 for long-term cycling (with a capacity retention of ∼94.7% after 100 cycles).
