Principles and characteristics of vanadium redox flow battery, a novel energy storage system, were introduced. Compared with Fe Cr redox battery, Ni Cd battery and lead acid battery, the vanadium battery performed higher energy density, longer operating life and more simple sturcture as well as the possibility of “instant recharge” by replacing its electrolytes. All vanadium redox flow systems were used for various applications, such as power load leveling, especially for electric vehicles. The development of vanadium redox flow battery were also discussed as well as the structure of single vanadium cell and 1 kW vanadium battery pack. Research of vanadium battery is very necessary in China due to the rich vanadium resources there. It is pointed out that the key technologies of developing vanadium redox flow cell were to improve the activity of its electrode materials and to select the proper separator.
