Study on the Electrolyte Added Chlorosulfuric Acid for All-vanadium Redox Flow Battery OH, YONG-HWAN; LEE, GEON-WOO; RYU, CHEOL-HWI; HWANG, GAB-JIN;
The electrolyte added the chlorosulfuric acid () 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 was higher than that in the electrolyte non-added . The thermal stability of the pentavalent vanadium ion solution, which was tested at , increased by adding . The performances of VRFB using the electrolyte added and non-added were measured during 30 cycles of charge-discharge at the current density of . An average energy efficiency of the VRFB was 72.5%, 82.4%, and 81.6% for the electrolyte non-added , added 0.5 mol of , and added 1.0 mol of , respectively. VRFB using the electrolyte added was showed the higher performance than that using the electrolyte non-added .
