Influence of the temperature on the polarization curve, cyclic efficiency, charge-discharge capacity and self-discharge performance of vanadium redox flow battery was studied in temperature range 15℃~35℃ by using a 10-cell stack, and the mechanism was analyzed. The results show that, in the process of temperature rising, the current efficiency decreases, and voltage efficiency, charge-discharge capacity and self-discharge rate all gradually increase. In order to ensure stable operation of the vanadium battery, the temperature should be strictly controlled in the actual application.
