초록 | The electrolyte added the chlorosulfuric acid ( $HSO_3Cl$ ) as an additive was tested for the electrolyte in all-vanadium redox flow battery (VRFB) to increase the thermal stability of electrolyte. The electrolyte property was measured by the CV (cyclic voltammetry) method. The maximum value of a voltage and current density in the electrolyte added $HSO_3Cl$ was higher than that in the electrolyte non-added $HSO_3Cl$ . The thermal stability of the pentavalent vanadium ion solution, which was tested at $40^{ circ}C$ , increased by adding $HSO_3Cl$ . The performances of VRFB using the electrolyte added and non-added $HSO_3Cl$ were measured during 30 cycles of charge-discharge at the current density of $60mA/cm^2$ . An average energy efficiency of the VRFB was 72.5%, 82.4%, and 81.6% for the electrolyte non-added $HSO_3Cl$ , added 0.5 mol of $HSO_3Cl$ , and added 1.0 mol of $HSO_3Cl$ , respectively. VRFB using the electrolyte added $HSO_3Cl$ was showed the higher performance than that using the electrolyte non-added $HSO_3Cl$ . |
