ent aqueous flow battery utilizing quinone couples has been developed jointly by the Gordon, Aspuru-Guzik and Aziz (SEAS) groups, displaying a remarkable >99% storage capacity retention per cycle. No precious metal electrocatalysts are necessary. The Harvard Gazette reports that the quinone identified for the study, 9,10-anthraquinone-2,7-disulfonic acid, is similar to one in rhubarb. On January 14th, Professors Gordon and Aziz described the potential benefits of their low-cost battery in a Fox Business newscast.
