The results show that the temperature decreases during charging and increases during discharging. And the capacity, VE and SOC range increase, while the over-potential, CE and average pressure loss decrease with the increment of average temperature. The temperature is a very important parameter for an operating vanadium redox flow battery (VRFB).
Vanadium redox flow batteries (VRFBs) are one of the most promising technologies for renewable energy storage. However, complex thermal issues caused by excessive heat generation during high-rate operations and various heat transfer behaviors in diverse climates dramatically affect the efficiency and stability of VRFBs.
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.
