Abstract

This paper examined HCL and H2SO4 Mixed Acid as the Supporting Electrolyte for Vanadium Redox Flow Battery. The results of Cyclic Voltammetry (CV) and electrochemical impedance spectroscopy (EIS) showed that the MAS sample had a better electrochemical activity than Pristine sample. At 20mAcm-2, VRFB with MAS sample exhibited a better discharge capacity than pristine sample. Moreover, the VFRB with MAS sample achieved higher average energy efficiency (81.26%) compared to the pristine cell (75.62%) and exhibited excellent cycling stability.
