Vanadium Pentoxide Powder

Vanadium pentoxide powder (V2O5) is an important chemical raw material with excellent physical and chemical properties. V2O5 is high purity when its purity is greater than 99.5%. It is the basic raw material for preparing high-purity metal vanadium and high-purity vanadium compounds.

V205 Powder

In recent years, with the continuous advancement of science and technology, strategic emerging technologies such as all-vanadium redox flow batteries for large-scale energy storage in photovoltaic, wind power and other new energy and microgrid fields, high-performance lithium-ion batteries based on lithium vanadate series and advanced vanadium-based alloys have emerged. The industry has increasingly higher requirements for the purity of vanadium products, resulting in an increasingly strong demand for high-purity vanadium pentoxide.

1. Energy storage materials

      (1) Vanadium flow battery

      Vanadium flow batteries utilize the redox reactions of vanadium ions in different valence states to achieve the mutual conversion of chemical energy and electrical energy. Vanadium electrolyte is an aqueous solution of vanadium sulfate (VOSO4), which is an electrical energy carrier. The purity of VOSO4 must be above 99.9% (to avoid the impact of impurity ions on the battery). VOSO4 is prepared from high-purity V2O5 using a chemical reduction method.

(2) Vanadium-based hydrogen storage materials

       Vanadium (V)-based solid solution hydrogen storage alloy has a body-centered cubic (BBC) structure. The theoretical hydrogen absorption capacity reaches 3.8%, which is much larger than AB5 type (1.4%) and AB type (1.86%). It can achieve rapid reversibility at room temperature. There are three main systems for absorbing and releasing hydrogen: V-Ti-Fe, V-Ti-Mn and V-Ti-Cr. Among them, V43.5Ti49Fe7.5 has the largest hydrogen absorption capacity, reaching 3.9%.

Vanadium catalysts are widely used in sulfuric acid production, synthesis of organic chemical raw materials in the petroleum industry, and flue gas desulfurization and denitrification treatment. The active components of vanadium catalysts commonly used in industry include vanadium oxides, chlorides, complexes, etc. Catalysts containing high-purity V2O5 as the main component are effective in almost all oxidation reactions.

      The catalyst usually contains 5% to 10% V2O5, and also contains K2O or Na2O to increase the activity of the vanadium catalyst. Diatomaceous earth is used as a carrier to increase the surface area of the catalyst active component in contact with the gas. Some vanadium catalysts also contain antimony oxide, tin oxide, aluminum oxide and iron oxide. At present, there are more than 20 vanadium catalyst manufacturers in my country, with a production capacity of more than 20 kt/a.
