Vanadium battery, also known as Vanadium redox flow battery (VRFB), is mainly divided into two parts: stack and electrolyte. Stack is a place where electric energy and chemical energy are converted to each other; The electrolyte stores electric energy and circulates during operation.

Application of Vanadium redox flow battery:Vanadium battery is one of the excellent green environmental protection batteries with strong development momentum at present (its manufacturing, use and waste process do not produce harmful substances).

Application of vanadium in all vanadium redox flow battery:Vanadium is a magical metal, its valence states are 2+, 3+ and 5+, and element vanadium is rare.
