“…[42][43][44] Several studies showed that the partial substitution of position B, which is in most cases nickel, affects remarkably the discharge capacity and cyclic stability of electrodes. 45,46 In the literature, various monosubstitutions (e.g., Al, 47 Cu, 48 Mn, 49 Zn, 50 Co, 51 Fe, 52 Sn, 53 and Rh) were studied. 54 For example, Merzouki et It was also noticed that the tri-substituted compound LaNi 3.55 Mn 0.4 Al 0.3 Co 0.75 had the best stability for 1000 cycles.…”

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.

Mechanical alloying (MA) is one of the most promising methods in the development of intermetallic alloys and their scientific research. In this paper, elemental powder mixtures of Ca, Ni, and Mn of nominal composition CaNi5‐xMnx (with x = 0.3, 0.5, and 1) were elaborated by MA technique during different milling times (2–60 h). Structural, morphological, and electrochemical changes were investigated by X‐ray diffraction (XRD), scanning electron microscopy, and Ec‐Lab galvanostat, respectively. The XRD test indicated that each alloy has Ni and CaNi3 or CaNi5 phases. In addition, the particle size of the ground powders is decreased with increasing milling time. Furthermore, all alloys have a very high activation capacity, whereby the activation capacity can be fully realized during the first cycle. The results showed that the most significant value of discharge capacity for all alloys was 40 h.

The hydrogen-storage purification is studied with hydrogen-storage alloy, LaNi5, as the purification agent, and its design and optimization method is established based on the integration of hydrogen network. Relationships among the hydrogen-saving capacity of unit hydrogen-storage material, the required weight of hydrogen-storage material, hydrogen-storage time, and purification feed purity are deduced and used in the design and optimization. An optimization procedure is proposed to identify the optimal purification feed, the maximum hydrogen utility savings, the amount of required hydrogen-storage material, and the hydrogen absorption time. The hydrogen networks of two refineries are optimized by the proposed method. With the designed hydrogen-storage purification units, their hydrogen utility consumption can be reduced by 23.11% and 44.69%, respectively. In both cases, the optimal purification hydrogen feed purity, the optimal hydrogen recovery and the consumption of LaNi5 hydrogen-storage material are identified; the economic performance of the hydrogen-storage purification is compared with that of pressure swing adsorption.
