Hydrogen storage properties of TiMn2-based alloys

Laves phase hydrogen storage alloys for super-high-pressure metal hydride hydrogen compressors

“…Liu et al [10] and Guo et al [11] reported the same results in their studies on TiMn 2 -based hydrogen storage alloys. As analyzed in Section 3.1, the partial substitution of Cr by Ti induces to the expansion of the cell volume in TiCr 1.6-x Mn 0.2 Fe 0.2 alloys, resulting in enlarging the volume of interspace for hydrogen accommodation.…”

“…sis, and kinetics [4][5][7][8]. Multi-substituted (Ti, Zr)(Mn, V) 2 alloys exhibit sloping plateaux even for well annealed samples [7][8].…”

Structure, morphology and hydrogen storage properties of composites prepared by ball milling Ti0.9Zr0.2Mn1.5Cr0.3V0.3Ti0.9Zr0.2Mn1.5Cr0.3V0.3 with La–Mg-based alloy

“…Another shortcoming is that the hydrides of these alloys possess large hysteresis effect [11,12]. In order to eliminate these disadvantages, many efforts have been exerted on these alloys, for example, the partial substitutions of Ti or/and Mn with some elements [10,13,14] in TiMn 2 -based Laves phase alloys.…”

“…However, the major problem of Ti-Mn alloys is * Corresponding authors. Tel./fax: +86 411 84379213. their higher equilibrium plateau pressure [10], which limits their practical applications. Another shortcoming is that the hydrides of these alloys possess large hysteresis effect [11,12].…”
