Overview

Modification with TiV improves hydrogen storage kinetics and thermodynamics in Mg-Ni alloys, suggesting potential applications.

Key Points

  • The TiV-modified Mg-20Ni composite achieved 3.0 wt % hydrogen desorption within 40 minutes at 225 °C.
  • Differential scanning calorimetry demonstrated a reduced desorption activation energy of 82.0 kJ/mol compared to the baseline Mg-20Ni system.
  • High-energy ball milling was utilized to fabricate TiV alloy for integration with Mg-Ni in a composite system.
  • The study reveals the importance of synergistic interactions between Ti/V and Ni in optimizing hydrogen storage properties.
