In Ti–Zr–Mn–Cr–Fe alloys, increased non-stoichiometric Mn and Cr raises the equilibrium plateau pressure, flattens the plateau region, and slightly reduces hydrogen content. The optimized x = 0 with y = 0 alloy maintains 96.2% capacity retention after 500 hydrogenation–dehydrogenation cycles.

The MgH₂–LiH composites with different composition ratios were prepared by different ball milling times, and the hydrogen generation performances of the composites were investigated and compared.

Effects of preparation methods on hydrogen storage properties of Ti _0.75 Zr _0.25 Mn _0.9 CrFe _0.1 alloy were studied. Melt-spinning improves microstructure uniformity, flattens the hydrogen absorption plateau, and enhances pulverization resistance.
