As the important support of smart grid construction, all vanadium flow batteries were widely used in power generation, transmission, substation, power distribution and utilization. As the active substance of all vanadium flow batteries, electrolyte determined the total store energy of all vanadium flow batteries. Electrolyte as an important part of all vanadium flow batteries, its performance directly affected the efficiency of vanadium flow batteries. To proceed from the two important factors of improving the performance of electrolyte, temperature and the concentration of electrolyte were summarized, the principle of temperature and concentration affecting the electrolyte performance were introduced. The related research in recent years at home and abroad were summarized.
