Long term performance evaluation of a commercial vanadium flow battery

The all-vanadium flow battery (VFB) employs V 2 + / V 3 + and V O 2 + / V O 2 + redox couples in dilute sulphuric acid for the negative and positive half-cells respectively. It was first proposed and demonstrated by Skyllas-Kazacos and co-workers from the University of New South Wales (UNSW) in the early 1980s [7], [8]. Using vanadium as a

To improve the operation efficiency of a vanadium redox flow battery (VRB) system, flow rate, which is an important factor that affects the operation efficiency of VRB, must be considered. The existing VRB model does not reflect the coupling effect of flow rate and ion diffusion and cannot fully reflect the operation characteristics of the VRB system.
