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.
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.
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.

Previous studies have demonstrated that the electrolyte temperature of an all-vanadium redox flow battery (VRB) has a significant influence on the safety and efficiency of the battery. Therefore, an effective cooling strategy is required, especially for large-scale batteries.
Vanadium redox flow battery (VRFB), in which vanadium is used as active energy storage material on both positive and negative sides, is perhaps the most developed redox flow battery (RFB) for large-scale renewable energy storage integrated into the electricity grid as compared to other types of RFBs [1, 2, 3, 4, 5].
