Vanadium nitride, VN, is a chemical compound of vanadium and nitrogen. Vanadium nitride is formed during the nitriding of steel and increases wear resistance. [1] Another phase, V 2 N, also referred to as vanadium nitride, can be formed along with VN during nitriding. [2] VN has a cubic, rock-salt structure.

Pissoort mentioned the possibility of VRFBs in the 1930s. [9] NASA researchers and Pellegri and Spaziante followed suit in the 1970s, [10] 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.

Vanadium pentoxide is a commercially important catalyst for the production of sulfuric acid, a reaction that exploits the ability of vanadium oxides to undergo redox reactions. [2] The vanadium redox battery utilizes all four oxidation states: one electrode uses the +5/+4 couple and the other uses the +3/+2 couple. Conversion of these oxidation ...
