Pissoort mentioned the possibility of VRFBs in the 1930s. NASA researchers and Pellegri and Spaziante followed suit in the 1970s, but neither was successful. Maria Skyllas-Kazacos presented the first successful demonstration of an All-Vanadium Redox Flow Battery employing dissolved vanadium in a solution of sulfuric acid in the 1980s. Her design used sulfuric acid electrolytes, and was patented by the University of New South Wales
