Multicomponent AB5 hydrides are attractive replacements for the cadmium electrode in nickel-cadmium batteries. The archetype compound of the AB~ alloy class is LaN%, but in a typical battery electrode mischmetal is substituted for La and Ni is substi

A number of LaNi{sub 5}-based intermetallics with Ce, Sn, and Co substitutions were prepared by the arc-melting technique and tested as electrodes in Ni/MH{sub x} batteries. Sn and Co substitution expand the unit cell and lower the plateau pressures

The metal hydride (MH{sub x}) electrode is the negative electrode in one of the most advanced rechargeable batteries (i.e. nickel/metal hydride). The objective of this study is to obtain insight on the mechanism of the hydriding/dehydriding reaction

The oxidation behaviour of nickel containing AB 5 type intermetallic compounds LaNi 5 and CaNi 5 has been studied in an oxygen atmosphere by thermogravimetric (TG) and differential thermal analysis (DTA). The TG of LaNi 5 showed complete oxidation of

The FeTi intermetallic compound, when oxidised at various temperatures, exhibits some interesting properties. XRD analysis of the treated samples indicates the formation of FeTiO 3 and Fe 3 O 4 phases at 973 K. ESR and DRS studies on the alloy sample

Our research examines the efficacy of tin additions to LaNi5 in improving the hydrogen storage capacity of the material during charging/discharging. Alloys were prepared using high energy ball milling (mechanical alloying), a technique superior to ar

The oxidation behaviour of the AB5 type intermetallic compounds CaNi5 and LaNi5 has been studied at different temperatures ranging from 100 to 800� C. The kinetic results indicate that the element A (Ca, La) is first oxidized rapidly followed by sl

Impurities in hydrogen affect the storage capacity of intermetallic systems. Carbon monoxide interacts with nickel-containing intermetallics such as CaNi 5 to give volatile nickel carbonyl which leads to a fall in the transition metal content, the hy

The Ca 2p, Ni 2p and O 1s emissions of the air-exposed sample of CaNi5 indicate that all the calcium and most of the nickel are present in the oxidized state. Interestingly, it is observed that all the peaks are shifted by 3 to 4 eV towards higher bi

X-ray photoelectron spectroscopic studies on the activated pure CaNi5 alloy as well as the hydride formed at 1 atm pressure and room temperature, CaNi5H4.8, showed that on activation calcium segregates to the surface and forms the oxide, whereas most
