Abstract
1-Butyl-3-methylimidazolium tetrafluoroborate(BMIMBF4)was used as the additive in anode electrolyte for vanadium redox flow battery(VRB).Its electrochemical performance and stability were investigated by cyclic voltammetry(CV),electrochemical impedance spectrum(EIS),charge-discharge measurement and examination of stabilization.The results indicated that the electrochemical activity and stability of the anode electrolyte were improved by adding BMIMBF4.The electric capacity of unit volume and the energy efficiency were also increased.
