The effects of the sulfate-methanesulfonic acid mixed electrolytes on the electrochemical performance, stability, kinetic viscosity and cell performance of the negative electrolytes are studied. The results indicate the sulfate-methanesulfonic acid mixed electrolytes could improve the reversibility of the V(II)/V(III) redox couple, delay the time for crystal at low temperature, and decrease the kinetic viscosity of the electrolytes. However, it would decrease the coulombic efficiency of battery, promote the migration of the vanadium ion, and accelerate the decay of capacity and energy.
Key words： Vanadium battery; methanesulfonic acid; negative electrolyte
