· JVASP-105351· V4Os

V₄O₅ is a vanadium oxide compound belonging to the family of reduced vanadium oxides, which are of significant interest in materials science and electrochemistry research. This material is primarily investigated for energy storage applications, catalysis, and as a precursor or intermediate phase in vanadium-based functional materials, where its mixed-valence vanadium chemistry offers potential advantages in ionic transport and electron conduction. Vanadium oxides in this compositional range are notable for their structural flexibility and redox properties, making them candidates for next-generation battery technologies and catalytic systems, though V₄O₅ itself remains largely in the research and development phase rather than established high-volume industrial production.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
