Solid State Ionics

Introduction to Solid State Ionics: Phenomenology and Applications presents a pedagogical, graduate-level treatment of the science and technology of superionic conductors, also known as fast ion conductors or solid electrolytes. Suitable for physics, materials science, and engineering researchers and students, the text emphasizes basic physics and

In this book, recent progress in batteries is firstly reviewed by researchers in three leading Japanese battery companies, SONY, Matsushita and Sanyo, and then the future problems in battery development are stated. Then, recent development of solid state ionics for batteries, including lithium ion battery, metal-hydride battery, and fuel cells, are reviewed. A battery comprises essentially three components: positive electrode, negative electrode, and electrolyte. Each component is discussed for the construction of all-solid-state Batteries. Theoretical understanding of properties of battery materials by using molecular orbital calculations is also introduced.

This volume presents a comprehensive collection of state-of-the-art advances in the field of solid state ionic materials and the design, fabrication and performance of devices that use them, such as lithium batteries, gas sensors, fuel cells, supercapacitors and electrochromic displays. These electrochemical devices are becoming pervasive in our technologically driven lifestyles.The book includes research activities being carried out in the new millennium, through special keynote addresses, as well as invited and contributed papers, related to experimental and theoretical modeling in solid state ionics. The excellent coverage of topics arranged in such a fashion helps students and beginners to understand the field with enthusiasm. It also encompasses various experimental techniques often employed in solid state ionics research, such as XRD, XPS, hole-burning spectroscopy, EDAX, EXAFS, SEM, thermal analysis techniques, ac-impedance spectroscopy and other electrochemical techniques such as cyclic voltammetry, galvanostatic and potentiostatic electrochemical techniques. Theoretical and applied aspects of mixed conduction for applications mainly in solid oxide fuel cells occupy a portion of the text. Finally, this volume demonstrates the amount of research activities being carried out in this application-oriented field.Solid State Ionics will be of interest to all in the solid state ionics community, including chemists, physicists, materials scientists and electrochemists, both in industry and in research.

Researchers in the new interdisciplinary field of solid state ionics will find this book indispensable because * it is one of the first volumes to consider the whole concept of solid state ionics, ranging from the research of solid electrolytes to the investigation and modelling of mixed conductors * it covers the fundamentals, materials and applications of solid state ionics * it presents mixed conduction and related materials in separate chapters * it offers a carefully thought out balance between traditional achievements and recent developments. Specialists and newcomers will appreciate the emphasis on applications and will find the book a handy reference work and fertile source of ideas for future research.

The field of solid state ionics is multidisciplinary in nature. Chemists, physicists, electrochimists, and engineers all are involved in the research and development of materials, techniques, and theoretical approaches. This science is one of the great triumphs of the second part of the 20th century. For nearly a century, development of materials for solid-state ionic technology has been restricted. During the last two decades there have been remarkable advances: more materials were discovered, modem technologies were used for characterization and optimization of ionic conduction in solids, trial and error approaches were deserted for defined predictions. During the same period fundamental theories for ion conduction in solids appeared. The large explosion of solid-state ionic material science may be considered to be due to two other influences. The first aspect is related to economy and connected with energy production, storage, and utilization. There are basic problems in industrialized countries from the economical, environmental, political, and technological points of view. The possibility of storing a large amount of utilizable energy in a comparatively small volume would make a number of non-conventional intermittent energy sources of practical convenience and cost. The second aspect is related to huge increase in international relationships between researchers and exchanges of results make considerable progress between scientists; one find many institutes joined in common search programs such as the material science networks organized by EEC in the European countries.

The main motivation for the organization of the Advanced Research Workshop in Belgirate was the promotion of discussions on the most recent issues and the future perspectives in the field of Solid State lonics. The location was chosen on purpose since Belgirate was the place were twenty years ago, also then under the sponsorship of NATO, the very first international meeting on this important and interdisciplinary field took place. That meeting was named "Fast Ion Transport in Solids" and gathered virtually everybody at that time having been active in any aspect of motion of ions in solids. The original Belgirate Meeting made for the first time visible the technological potential related to the phenomenon of the fast ionic transport in solids and, accordingly, the field was given the name "Solid State lonics". This field is now expanded to cover a wide range of technologies which includes chemical sensors for environmental and process control, electrochromic windows, mirrors and displays, fuel cells, high performance rechargeable batteries for stationary applications and electrotraction, chemotronics, semiconductor ionics, water electrolysis cells for hydrogen economy and other applications. The main idea for holding an anniversary meeting was that of discussing the most recent issues and the future perspectives of Solid State lonics just twenty years after it has started at the same location on the lake Maggiore in North Italy.

Defects play an important role in determining the properties of solids. This book provides an introduction to chemical bond, phonons, and thermodynamics; treatment of point defect formation and reaction, equilibria, mechanisms, and kinetics; kinetics chapters on solid state processes; and electrochemical techniques and applications. * Offers a coherent description of fundamental defect chemistry and the most common applications. * Up-to-date trends and developments within this field. * Combines electrochemical concepts with aspects of semiconductor physics.

Solid state ionics is concerned with the science and technology of ions in motion in the solid state. Ions in motion may also involve electrons, depending on the materials and surroundings. These days, solid state ionics is finding an increasing variety of applications. The knowledge of solid state ionics is also extensively mobilized to protect, predict or elongate the lifetime of structural materials in harsh service conditions and to improve the performance reliability of devices. Furthermore, solid state ionics is now being combined with the emerging nanotechnology to produce new knowledge and applications. This book covers the following topics: fuel cells and membranes; batteries; sensors and electrochromics; fundamentals of ionic transport and defect chemistry; cation/anion/mixed ionic electronic conductors.

"The topics covered in this volume include the materials aspect of crystalline and composite electrolytes, polymers, and glasses. Twenty-one invited and forty-five contributed papers emphasize ionic transport, dielectric studies, electronic and mixed conductors, proton conductors, cathode materials, electrochromism, experimental techniques and application of solid state ionic materials in batteries, fuel cells, electrochromic displays and sensors."--Publisher's website.

In recent years Solid State Ionics have attracted considerable interest due to the important role which they may play in the future of microelectronics and eventually in other fields of energy storage. This volume presents papers on the theory, experiments and applications in this field including: New materials; Insertion compounds; Transport; Structure; Polymeric electrolytes; Mixed conductors; Protonic and oxygen conductors; and electrochromics.
