摘要: >> The electrolyte added the chlorosulfuric acid (HSO3Cl) as an additive was tested for in all-vanadium redox flow battery (VRFB) to increase thermal stability of electrolyte. property measured by CV (cyclic voltammetry) method. maximum value a voltage and current density HSO3Cl higher than that non-added HSO3Cl. pentavalent vanadium ion solution, which at 40°C, increased adding performances VRFB using were during 30 cycles charge-discharge 60 mA/cm 2 . An average energy efficiency 72.5%, 82.4%, 81.6% HSO3Cl, 0.5 mol 1.0 respectively. showed performance
