All vanadium liquid flow battery is a liquid redox renewable battery with metal vanadium ion as the active material.

Because the electrolyte ions of vanadium flow battery exist in aqueous solution, thermal runaway, overheating, combustion and explosion will not occur. At the same time, vanadium batteries support frequent charge and discharge, which can be charged and discharged hundreds of times a day. The liquid electrolyte will not cause explosion and battery capacity reduction due to overcharge and discharge.

As the place of reaction, the stack of vanadium battery is separated from the storage tank of electrolyte, which fundamentally overcomes the self discharge phenomenon of traditional battery. The power only depends on the size of the stack, and the capacity only depends on the electrolyte storage and concentration. The design is flexible. When the power is constant, to increase the energy storage capacity, you only need to increase the volume of electrolyte storage tank or increase the volume or concentration of electrolyte, without changing the size of the stack. At the same time, the power can be increased by increasing the power of the stack and the number of the stack, and the storage capacity can be increased by increasing the electrolyte, which is convenient for the expansion of the battery scale. It can be used to build kilowatt level to 100 megawatt level energy storage power stations with strong adaptability.
