Formation of nanostructured LaMg2Ni by rapid quenching and intensive milling and its hydrogen reactivity

The formation of the nanostructured orthorhombic LaMg2Ni phase using the melt-spinning and the intensive ball milling routes has been studied for the La25Mg50Ni25 and La20Mg50Ni30/sub

Effect of chemical and external pressure on the structure of intermetallic compound CeNi

Neutron powder diffraction was employed to study the structural modifications of the intermediate-valence compound CeNi at room temperature induced by either chemical or external pressure. For the first time we were able to record the diffraction pattern resulting from the pressure-induced first-order phase transition occurring in CeNi at 300 K. At pressure P = 2 GPa we observe the coexistence of two phases while only single pressure-induced phase is visible at P = 5 GPa. The results obtained are indicative of a higher symmetry of the collapsed structure as compared to the CrB-type ambient pressure structure of CeNi. The critical pressure range around 2 GPa is found to be agreement with the previous estimation derived from the thermopower measurements.

Cycling durability and degradation behavior of La-Mg-Ni-Co-type metal hydride electrodes

The cycling durability and degradation behavior of the La-Mg-Ni-based hydrogen storage alloys La0.7Mg0.3Ni 3.4-xCoxMn0.1 (x = 0, 0.75, 1.3) during charge/discharge cycling has been systematically studied by XRD, SEM, EIS, XPS and AES measurements. The reasons for the improvement of the cycling stability of the alloy electrodes with increasing Co content have also been analyzed and discussed. The results show that the pulverization of the alloy particles and the oxidation/corrosion of the active components of the alloys during charge/discharge cycling in the alkaline electrolyte are the two main factors responsible for the fast capacity degradation of the La-Mg-Ni-based alloy electrodes, and the capacity degradation mechanism can be decomposed into three consequent stages, i.e., the pulverization and Mg oxidation stage, the Mg and La oxidation stage and the oxidation and passivation stage. With the increase in Co content, the cell volume expansion ratio ΔV/V of the two main phases during hydrogenation/dehydrogenation was obviously decreased, which results in a reduction of the pulverization of the alloy particles and, consequently, in an increase in the charge and discharge efficiency and a decrease in the rate of contact of the fresh alloy surface with alkaline electrolyte and a subsequent lower rate of oxidation/corrosion. It is believed to be the most important reason responsible for the improvement of the cycling stability of the alloy electrodes with increasing Co content.
