From the point of view of hydrogen, desorption metal hydrides are extremely complex and interesting. Various metal hydrides differ so much, range in terms of decomposition temperatures and pressures and look like materials from separate classes. Many research articles are devoted to metal hydrides; many of them study the kinetics of dehydriding. However, there is still no complete understanding of the processes that govern kinetics. The reason is for the high number of factors that influence the rate of hydride decomposition and hydrogen desorption. First of all, properties of metal hydrides are diverse. The number of hydride phases, decomposition rates and ranges of absorbed energy are very different. The rates of hydrogen desorption, diffusion and phase transition also can influence the kinetics of dehydriding. The aim of this book is to summarise the authors research of dehydriding kinetics with electronic structures of the materials taken into account, and to determine which elementary processes influence the decomposition rates. The book is not a reference guide on the dehydriding rates of constants. Even more so, in order to keep the subject as simple as possible, the authors restrict the discussion only to binary hydrides when talking about basic dehydriding laws. It is possible, however, that ternary and more complex hydrides have their own unique properties. The authors describe experimental results through physically clear and well studied processes, such as desorption, diffusion, reaction of hydride decomposition, etc. as well as by using conservation laws. On the other hand, describing the entire process in the most general way, taking into account all of the possible reactions and excluding some on the grounds of experimental results, also seems unsound. The authors believe that complexity of models must be comparable to that of experimental data; additional factors should be taken into account only in order to improve poor fitting. The following factors seem the most important: Electronic properties of the hydride (type of bonding); phase morphology; incubation and nucleation; physically reasonable elementary processes mentioned above (diffusion, adsorption and desorption, decomposition and formation of the hydride phase, etc.); and the variety of powder particles. Over recent years, much effort has been made to activate the decomposition of magnesium and aluminium hydrides with the hope of finding appropriate materials for keeping hydrogen in solids aboard a vehicle. Most of the research dealt with mechanochemical activation (ie: ball milling in the presence of catalysts, often in hydrogen). The choice of catalytic materials is not always logical; this was one more reason for systemising the dehydriding kinetics. Naturally, activated materials must follow the general pattern of decomposing metal hydrides. A separate section is devoted to the activation of magnesium and aluminium hydrides; aside from mechanochemical, we also discuss the thermal and photoactivation of these materials.

Metal Hydrides focuses on the theories of hydride formation as well as on experimental procedures involved in the formation of hydrides, the reactions that occur between hydrides and other media, and the physical and mechanical properties of the several classes of hydrides. The use of metal hydrides in the control of neutron energies is discussed, as are many other immediate or potential uses, e.g., in the production of high-purity hydrogen and in powder metallurgy. It is hoped that this book will serve as a valuable reference to students, research professors, and industrial researchers in metal hydrides and in allied fields. Selected chapters may serve specialists in other fields as an introduction to metal hydrides. The information contained herein will also be of lasting and practical value to the metallurgist, inorganic chemist, solid-state physicist, nuclear engineer, and others working with chemical or physical processes involving metal-hydrogen systems.

Hydrides: Types, Bonds and Applications first proposes metal hydrides as a fascinating class of compounds due to the small mass and size of hydrogen. Its medium electronegativity causes a large flexibility in terms of metal-ligand interactions, resulting in a vast variety of possible compositions, chemical bonding, crystal structures and physical properties. However, numerous unsolved problems remain on our way towards a sustainable, carbon free energy system based on renewable energy and on hydrogen as a future energy carrier. Thus, the authors present the structural details of alkali, alkali earth based selected tetra-boro hydrides. Selected hydrides have recently been suggested for applications in optoelectronics and as solid electrolytes for battery applications. Their use in optoelectronic devices depends on their stability with respect to doping, solubility of shallow donors and acceptors, electrical and optical properties. The authors describe the nature of the bonding in hydrides, and show how these affect the properties of these materials, focussing on application in the energy storage and in the transportation sector. Next, the features of gas discharge and plasma sources based on Penning trap with metal hydride cathodes are presented. In such devices, metal hydrides fulfill the functions of both a cathode and the solid-state generator of working gas. The authors determine that hydrogen desorbed from metal hydride significantly changes the properties of the discharge. This is expressed, for example, in the fact that the plasma source based on Penning trap with metal hydride cathode appears to generate current-compensated ion beams with the ability to control the energy of the extracted ions. Lastly, the book discusses metal hydrides obtaining in sintered electrodes of nickel-cadmium batteries with electrochemical methods by the way of electrolyte decomposition onto hydrogen and oxygen. It was shown that as a result of electrolyte decomposition, oxygen releases from batteries, while hydrogen partly releases and is partly (in virtue of its high diffusion permeability) accumulated in sintered matrices of electrodes of nickel-cadmium batteries in the metal hydrides form.
