Solid State Ionics

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.

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 chemistry as well as applications of electrochemical energy materials. The book focuses on fundamental phenomenological aspects, including crystal structure, phonon dispersion, electronic band structure, defects, disorder, nonstoichiometry, non-equilibrium thermodynamics, phase transitions, and statistical mechanics of iono-electron transport. It explains how the design, synthesis, and characterization of materials aid in optimizing diffusion coefficients and ionic conductivities. The author also describes important applications of solid state ionics, including solid state batteries, fuel cells, and electrochemical sensors.

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.

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.

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 book gives an authoritative introduction to the emerging science and technology of Solid State Ionics. It serves both as an introductory text book for graduate students and a reference book on the shelf of researches working on specific areas of solid state ionics.

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.

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.
