“…The classical example is LaNi 5 , which was reported in 1970 by van Vucht et al [231]. The AB 5 type metal hydrides are mainly used as hydride electrodes in Ni-MH batteries but they are also considered for hydrogen storage and purification [232,233,234,235]. One of the problems facing the AB 5 type metal hydrides is the slow first hydrogenation.…”

This paper is a collection of selected contributions of the 1st International Workshop on Mechanochemistry of Metal Hydrides that was held in Oslo in May 2018. In this paper, the recent developments in the use of mechanochemistry to synthesize and modify metal hydrides are reviewed. A special emphasis is made on new techniques beside the traditional way of ball milling. High energy milling, ball milling under hydrogen reactive gas, cryomilling and severe plastic deformation techniques such as High-Pressure Torsion (HPT), Surface Mechanical Attrition Treatment (SMAT) and cold rolling are discussed. The new characterization method of in-situ X-ray diffraction during milling is described.

“…Intermetallic compounds of the general formula AB 5 (A; rare earth element, usually La, B; transition (d-electron) metal(s), usually Ni) have been extensively investigated in recent years as possible hydrogen storage materials [1][2][3][4][5]. In the AB 5 type alloy, both La and Ni can be replaced by other elements: La by Ce, Pr, Nd or by mishmetal (Mm) [6][7][8][9][10]; and Ni by Mn, Zn, Cr, Fe, Co, Cu or even by Al and Sn [9,[11][12][13][14] to improve the hydrogen storage capacity, the stability of the hydride phase or the alloy corrosion resistance.…”

“…They used AB 5 type negative electrode substituted with a small amount of Fe, Cr, and Cu to reduce the cost of raw materials 32 . This electrode has good absorption/desorption properties such as suitable plateau pressure, 33,34 easy reversibility at moderate temperature–pressure and good hydration/dehydration kinetics 35,36 . AB 5 ‐type alloys are based on a LaNi 5 matrix 37,38 .…”

The present research work examines the electrochemical properties of CaNi4.8M0.2(MMg, Zn) type alloy applied as an anode in nickel metal hybrid batteries. Based on an extensive study of the CaNi4.8Mn0.2 compound prepared by mecano‐synthesis; under an argon atmosphere, with a variation of milling time and weigh ratio, using a Retsch PM400 type ball mill. The experimental results show that the excellent electrochemical properties were obtained for a milling time of 40 h and a ball‐to‐powder weight ratio equal to 8:1. Based on this study, we examined electrochemically the CaNi4.8M0.2(MMg, Zn, and Mn) compound according to the optimized parameters. Several methods, such as galvanostatic polarization and potentiodynamic polarization, were applied to characterize these electrodes. CaNi4.8M0.2(MMg, Zn, and Mn) electrodes were activated, respectively, during the first, second, and third cycles. The maximum discharge capacity was about 87, 60, and 96 mAhg−1 at ambient temperature. These electrochemical findings correlate with the kinetic results provided during a long cycle.
