How does temperature affect a vanadium redox flow battery?
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).
