TLDR
In this paper, a new concept of hydrogen absorbing alloy, called Laves phase related BCC solid solution, was proposed, which showed stability of hydrides and reaction kinetics almost identical to intermetallics such as laves phase alloys.Citations

Superior hydrogen storage in high entropy alloys.
TL;DR: It is demonstrated, for the first time to the best of the knowledge, that a high entropy alloy of TiVZrNbHf can absorb much higher amounts of hydrogen than its constituents and reach an H/M ratio of 2.5.

Hydrogen absorption in LaNi5 and related compounds: Experimental observations and their explanation
TL;DR: In this paper, a study of the change in hydrogen sorption properties caused by partially replacing La or Ni in LaNi5 by other metals is presented. But this study assumes that the more stable the original RNi5 compound, the weaker is the tendency to form a rNi5--hydride.

Hydrogen absorption properties of TiCrA (A ≡ V, Mo or other transition metal) B.C.C. solid solution alloys
TL;DR: In this article, the effect of the composition on the hydrogen-absorbing capacity and equilibrium dissociation pressure of binary alloys and ternary alloys with b.c. structures were measured.

Hydride formation rates of B.C.C. group V metals
TL;DR: In this paper, it was shown that the solution of small amounts of a second metal yields alloys which will react extremely rapidly with hydrogen at room temperature without activation, and that the second metal should have a radius which is at least 5% smaller than that of the solvent group V metal.

V-based solid solution alloys with Laves phase network: Hydrogen absorption properties and microstructure
TL;DR: In this article, a Laves phase was precipitated, forming a three-dimensional network along grain boundaries of a V-based solid solution main phase, and the increase in fresh surface area was very useful in enhancing the high-rate capability of the electrode.
