Synergistic binary catholyte design for enhanced electrochemical performance in membraneless hybrid flow batteries
A hydroquinone (HQ)/1,2-dihydroxybenzene-3,5-disulfonic acid (Tiron) binary catholyte system is developed for membraneless zinc hybrid flow batteries, leveraging sequential redox reactions with complementary potentials to enhance energy density and electrochemical kinetics. The HQ-Tiron system achieves an energy density of 21.4 W h L<sup>-1</sup> and a peak power density of 102.3 mW cm<sup>-2</sup>.
