Aziz. 2014. “Cycling of a Quinone-Bromide Flow Battery for Large-Scale Electrochemical Energy Storage.” ECS Transactions 61 (37) (September 29): 27–30. doi:10.1149/06137.0027ecst.1938-6737http://nrs.harvard.edu/urn-3:HUL.InstRepos:25984767We have demonstrated the performance of an aqueous redox flow battery composed of a negative electrode consisting of a redox couple between anthraquinone di-sulfonate and its corresponding hydroquinone, and a positive electrode consisting of a redox couple between hydrobromic acid and bromine. The peak power density is approximately 0.6 W/cm2. After 750 deep cycles, the average discharge capacity retention is 99.84% per cycle and the average current efficiency is 98.35%.en-USJournal Article2016-03-1610.1149/06137.0027ecst
