Vanadium pentoxide (V₂O₅) is a transition metal oxide semiconductor with moderate electrical conductivity and mixed-valence chemistry, widely used as a catalyst and in electrochemical devices. It is the primary industrial form of vanadium and serves critical roles in sulfuric acid production, organic synthesis catalysis, and energy storage applications such as vanadium redox flow batteries (VRFB). Engineers select V₂O₅ for its catalytic efficiency in oxidation reactions and its reversible intercalation behavior, making it valuable for rechargeable battery systems and smart window (thermochromic) coatings where its insulator-to-metal transition can be exploited.
