Redox flow battery with capacity retention of 99.98% per cycle

The battery was fabricated by Chinese scientists with a low-cost electrolyte made of a derivative of TEMPO, which is a well-known electroactive aminoxyl radical used with several applications in chemistry and biochemistry. According to the researchers, the battery shows high redox potential and is crossover-free.Scientists from the South China University of Technology have built an aqueous redox flow battery with a positive electrolyte made of the electroactive organic molecule called TEMPO, which they describe as a chemical compound with easily reversed oxidation states and a high potential for ...
