Summary: Understanding the relationship between the structure, composition, and hydrogenation properties of intermetallic hydrides is crucial for improving their hydrogen storage performance. The ability to form hydrides and control their interaction with hydrogen is determined by their chemical composition.

Computational calculations were also performed. The study revealed the mechanism of phase-structural transformation and the formation of unique metal-hydrogen bonding in the intermetallic alloy. At high pressures, a TiNiSi-type hydride was formed. The study also showed that scandium behaves similarly to the heavy rare earth metal holmium.

Summary: This paper investigates the electrochemical performance of Hf-modified Ti-Zr based AB2 Laves type metal hydride battery anode alloys. The alloys were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM), and the electrochemical performance was studied through PCT diagrams and electrochemical tests. The Hf content in the alloys affected the phase composition, electrochemical discharge capacities, exchange current densities, H diffusion rates, and hydrogen storage capacity. The presence of Hf resulted in a decrease in discharge capacities and exchange current densities, while the alloy with the lowest Hf content showed the highest H storage capacity. The modification of the intrinsic properties of the alloys with Hf substitution played a role in the observed effects.
