This dependence is of critical importance during battery operation; since the SOC of the solution for each half-cell electrolyte could be changed, the vanadium concentrations may differ accordingly because of the ionic diffusion processes across the membrane and thus the solution conductivities vary.
To gain an understanding of the general thermal behavior of vanadium redox flow batteries (VRFBs), we devised and tested a laboratory-scale single VRFB by varying the operating temperature. The voltage efficiency of the VRFB is found to increase from 86.5% to 90.5% at 40 mA/cm 2 when the operating temperature is increased from 15 °C to 55 °C.
Xiao et al. [ 7] investigated both the physical and electrochemical properties of vanadium electrolytes from 233.15 K to 323.15 K. The positive electrolyte is found to be stable at a low temperature, while the negative electrolyte behaves more stably at a high temperature.
A composition of 1.5 M vanadium solutions in 3.0 M total sulfate was selected and a range of − 10–50 °C was set as the operating temperature limits.
Within the realm of flow battery systems, the vanadium redox flow battery (VRFB) attracts the most attention due to its ability to avoid permanent cross contamination and bear deep charge and discharge. VRFBs have been extensively investigated over the past decade because of the above-mentioned advantages.
