Abstract

To optimize the anode electrolyte in vanadium halide redox flow battery, the viscosity, electrochemical impedance, cyclic voltammograms and steady polarization curve analysis have been studied. When the range of from 1.0 M to 1.5 M, the viscosity is small and the results of cyclic voltammograms, Electrochemical impedance spectroscopy and steady polarization curve show good reversibility of electrolyte. The sodium bromide concentration range from 1 M to 1.5 M is the suitable concentration range of sodium bromide.
