“…The hydriding and dehydridng enthalpies were determined to be À32.1 and 31.5 kJ/mol of H 2 from the van' Hoff plot. These values are close to the value of AE30 kJ/mol of H 2 for the LaNi 5 eH 2 system [10].…”

“…A magnesium-based hydride with relatively high capacity (Mg 2 Ni) was reported by Reilly and Wiswall in 1968 [61]. Later, roomtemperature hydrides such as the ternary hydrides TiFeH 2 and LaNi 5 H 6 were [62,63]. Since then, a huge number of intermetallic hydrides have been investigated.…”

Metal hydrides are promising candidates for many stationary and mobile hydrogen storage applications. Presently, the most common use of metal hydrides is as anode material in commercial nickel-metal hydrides (Ni-MH) rechargeable batteries which have replaced conventional nickel-cadmium batteries in many applications. A wide variety of Ni-MH batteries are now on the market with cell sizes ranging from 30 mAh to 250 Ah [1,2]. Some other applications are: hydrogen compression [3], aircraft fire-detectors [4], isotope separation [5], and hydrogen getters for microelectronic packages. Hydride formation is also used in the HDDR process (hydrogenation-disproportionation-desorption-recombination) for the synthesis of magnetic materials such as Nd 2 Fe 14 B [6]. A striking application is as a component of cryocoolers for the ESA Planck mission [7]. Another exciting new application is the use of metal hydrides for switchable mirrors [8]. As we can see, metal hydrides have a wide range of applications. However, most research and development is targeted towards two applications: batteries and hydrogen storage. The former is now widely exploited but the latter is still facing many technical problems. The main advantages of storing hydrogen in a metal hydride are the high hydrogen volumetric densities (sometimes higher than in liquid hydrogen) and the possibility to absorb and desorb hydrogen with a small change in hydrogen pressure [9].The physics of hydrogen in elemental metals was reviewed at the end of the 1970s in thebooksHydrogeninMetals,volumesIandII [10,11].The1970s alsosawtheemergence of the important field of intermetallic compounds as hydride materials. An in-depth review of this field can be found in Hydrogen in Intermetallic Compounds volumes I, and II [12,13]. A review of the propertiesand applications of hydrogen in metals can befound in the third volume of Hydrogen in Metals [14]. The basic properties of the metal-hydrogen system are discussed from a fundamental point of view by Fukai [15]. Although initial studies on nanocrystalline and amorphous metal hydrides were initiated around the 1980s [16], the real emergence of nanocrystalline metal hydrides as a new class of Handbook of Hydrogen Storage.
