We measure electrolyte concentration and state-of-charge in real time in an operating aqueous anthraquinone-based flow battery using in-line optical spectrophotometry. By capitalizing on the linear transition in absorption spectra between oxidized and reduced states, we show how discontinuous capacity fade rates in redox flow batteries can be caused by a… CONTINUE READING
