About 85% of the metal vanadium in the steel industry is added in the form of ferrovanadium and vanadium nitrogen alloy in steel production to improve the strength, toughness, ductility and heat resistance of steel. Vanadium containing high strength alloy steel is widely used in oil/gas pipeline, construction, bridge, rail and other production and construction. Vanadium containing high strength alloy steel mainly includes: high strength low alloy (HSLA) steel (synthesis); HSLA steel plate; HSLA steel; HSLA steel strip; Advanced high strength strip steel; Threaded reinforcing bars for construction; High carbon steel wire; Rail; Tools and die steel, etc.

In the aerospace industry, 8-10% of vanadium metal in the form of ti-al-vanadium alloy is used in aircraft engines, aerospace cabin skeleton, missiles, steam turbine blades, rocket engine shell and other aspects. Vanadium alloys are also used in magnetic materials, hard alloys, superconducting materials and nuclear reactor materials. Chemical industry, in the chemical field, vanadium is mainly used as a catalyst for the manufacture of sulfuric acid and vulcanized rubber, but also used to inhibit the generation of nitrous oxide in power plants. Other chemical vanadium products are mainly used in catalyst, ceramic colorant, developer, desiccant.

All vanadium flow batteries is a new type of energy storage and high efficient conversion device, the different valence state of vanadium ion solution respectively as the positive and negative active material, stored in a separate electrolyte storage tank, by an external stacked into the battery electrolyte pump body, pump in the different storage tank and the half cell cycle in closed loop flow, using ion exchange membrane as battery diaphragm, electrolyte solution parallel through the electrode surface and electrochemical reactions occur, through electric double plate collection and conduction current, make the chemical energy into electrical energy stored in the solution. This reversible process enables vanadium batteries to be charged, discharged and recharged successfully. Vanadium battery works.
