Abstract: The performance of vanadium flow batteries (VRFB) can be severely reduced when operating at low temperatures due to changing electrolyte properties. In this work, we develop a non-isothermal model of VRFB dynamics that takes into account changes in electrolyte viscosity depending on temperature.

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).
The operational temperature of vanadium electrolyte was extended to -5∼45 °C. Electrochemical characterization confirmed that WTR-electrolyte has comparable performance to the conventional electrolyte at 100 mA cm −2, while not sacrificing performance.
