Aqueous polysulfide-based flow batteries are candidates for large-scale energy storage but the sluggish reaction kinetics of the polysulfide electrolyte limit the operating current density and energy efficiency. A molecular catalyst, riboflavin sodium phosphate, is applied to catalyse polysulfide reduction, enabling the demonstration of long-life polysulfide-based flow batteries with high energy efficiencies.
