High-Purity Vanadium Dihydride Powder VH2 CAS 12713-06-3

Vanadium Dihydride (VH₂) is a reversible hydrogen storage material with exceptional hydrogen absorption capacity (up to 3.8 wt%) and thermal stability. This gray-black metallic compound operates at moderate temperatures (20-200°C), making it ideal for solid-state hydrogen storage systems, battery anodes, and nuclear moderation applications.

High Efficiency: Absorbs 2H per V atom at room temperature
Rapid Kinetics: 90% H₂ absorption within 5 minutes (at 50°C, 10bar)
Safety: Non-pyrophoric, unlike many metal hydrides
Tunable Pressure: Plateau pressure 0.1-10bar (20-100°C)
