[0002] At present, the all-vanadium liquid flow battery is a new type of energy storage battery with relatively young technology. It is particularly suitable for applications in large-capacity energy storage. Its basic principle is: the vanadium ion solutions with different valence states are stored in the positive and negative electrolyte storage tanks respectively, and the positive and negative electrolytes are provided to the battery modules separately through external pumps.
