Fullerene C76 as a novel electrocatalyst for VO2+/VO2+ and chlorine evolution inhibitor in all-vanadium redox flow batteries†
Abstract
We report, for the first time, the superior electrocatalytic activity of fullerene C76 towards VO2+/VO2+ in all-vanadium redox flow batteries. Results show a 99.5% and 97% decrease in charge transfer resistance, compared to treated and untreated carbon cloth. Suppression of chlorine evolution and good stability after 100 cycles are achieved.
