Vanadium redox battery. The vanadium redox (and redox flow) battery is a type of rechargeable flow battery that employs vanadium ions in different oxidation states to store chemical potential energy.
The present form (with sulfuric acid electrolytes) was patented by the University of New South Wales in Australia in 1986.[2] An earlier German Patent on a titanium chloride flow battery was registered and granted in July 1954 to Dr. Walter Kangro, but most of the development of flow batteries was carried out by NASA researchers in the 1970s.
