Kinetic behaviour of low-Co AB5-type metal hydride electrodes
TL;DR: The kinetic behavior of the LaNi3.55Mn0.4Al0.3Co 0.4Fe0.35 metal hydride, used as a negative electrode in the Ni/MH batteries, was investigated using electrochemical impedance spectroscopy (EIS) at different state of charge (SOC) as mentioned in this paper.

Palladium mixed-metal surface-modified AB5-type intermetallides enhance hydrogen sorption kinetics : research article
M.V. Lototsky,Alexander Nechaev,Volodymyr A. Yartys,Jan Ketil Solberg,Roman V. Denys,Vladimir Linkov +5 more
TL;DR: In this article, the influence of micro-encapsulation on the surface morphology and kinetics of hydrogen charging was investigated and it was found that palladium-nickel (Pd-Ni) co-deposition by electroless plating significantly improved hydrogen charging of the AB5-type intermetallides at low hydrogen pressure and temperature, after long-term pre-exposure to air.

Thermodynamic and hydrogen-induced structural properties of Ho1−xMmxCo2-hydrides
TL;DR: In this article, the structural properties of hydrogenated Ho1−xMmxCo2-hydrides were investigated using powder x-ray diffraction and the structural stability of these alloys upon repeated hydrogenation and dehydrogenation cycles was investigated.

Effect of long-term hydrogen absorption/desorption cycling on hydrogen storage properties of MmNi3.55Co0.75Mn0.4Al0.3
TL;DR: In this paper, the effect of a long-term hydrogen absorption/desorption cycling up to 2000 cycles on the hydrogen storage properties of MmNi(3.55), Co(0.75), MnNi(1.4), Al( 0.3) alloy was investigated.

Synthesis of Al-containing MmNi5 by mechanical alloying: Milling stages, structure parameters and thermal annealing
Sergio Alejandro Obregon,J.J. Andrade-Gamboa,J.J. Andrade-Gamboa,Marcelo R. Esquivel,Marcelo R. Esquivel +4 more
TL;DR: In this article, an improvement on the milling time-annealing process was proposed, which was correlated to the structural parameters obtained on the structure of the structure. But the optimization was not correlated to energy consumption at laboratory scale.
