Application

  • Vanadium(V) oxide is used in the preparation of vanadium alloys.
  • It is an oxidizing agent, commonly used as a catalyst in contact process (production of sulfuric acid) to oxidize sulfur dioxide to sulfur trioxide.
  • It is widely used as a host material for lithium-ion battery, sodium-ion battery, magnesium-ion battery and pseudocapacitors.
  • V2O5 is also used as the charge injection and extraction materials in organic electronic devices.
