Membrane-free chlorine redox flow battery for stationary storage
A US-Chinese research group has developed a full chlorine membrane-free redox flow battery that is claimed to achieve a round-trip energy efficiency of 91% at 10 mA/cm2 and an energy density of 125.7 Wh/L. The device is based on an aqueous electrolyte made of sodium chloride (NaCl) which uses chlorine (Cl2/Cl−) redox couple as the active material for the positive electrode.
