Superionic Solids and Solid Electrolytes: Recent Trends describes the fundamental aspects, unique properties, and potential applications of superionic solids and solid electrolytes. These materials significantly contribute to the development of the solid state ionics technology. This book is divided into 17 chapters, and begins with an overview of various materials, such as glasses, heterogeneous or dispersed phase conductors, proton conductors, Nasicon, and fluorites. These topics are followed by a discussion on the problems related with entropy effects, subsurface space charge, and defect formation parameters. Significant chapters deal with the phenomenological, fractal, molecular dynamics, fluctuations, and correlations in superionic solid and solid electrolyte materials. A chapter tackles the solid state battery applications of solid electrolytes. This text ends with a chapter on the prediction of the potentials of activity in superionics. This book will be of value to graduate students and researchers who are interested in the solid state ionics technology.

This book describes, for the first time in a modern text, the fundamental principles on which solid state electrochemistry is based. In this sense it is in contrast to other books in the field which concentrate on a description of materials. Topics include solid (ceramic) electrolytes, glasses, polymer electrolytes, intercalation electrodes, interfaces and applications. The different nature of ionic conductivity in ceramic, glassy and polymer electrolytes is described as are the thermodynamics and kinetics of intercalation reactions. The interface between solid electrolytes and electrodes is discussed and contrasted with the more conventional liquid state electrochemistry. The text provides an essential foundation of understanding for postgraduates or others entering the field for the first time and will also be of value in advanced undergraduate courses.

Defect solid state has been an area of major scientific and technological interest for the last few decades, the resulting important applications sus taining this interest. Solid electrolytes represent one area of defect solid state. The early work on defect ionic crystals and, in particular, the classic results of Kiukkola and Wagner in 1957 on stabilized zirconia and doped thoria laid the foundation for a systematic study of solid electrolytes. In the same year, Ure reported on the ionic conductivity of calcium fluoride. Since then, intense worldwide research has advanced our understanding of the defect structure and electrical conductivity of oxygen ion conductors such as doped zirconia and thoria and of the fluorides. This paved the way for thermo dynamic and kinetic studies using these materials and for technological applications based on the oxygen ion conductors. In the last few years we have seen the emergence of two new classes of solid electrolytes of great signifi cance: the fJ-aluminas and the silver ion conductors. The significance of these discoveries is that now (i) solid electrolytes are available which at room temperature exhibit electrical conductivity comparable to that of liquid electrolytes, (ii) useful electrical conductivity values can be achieved over a wide range of temperature and ambient conditions, and (iii) a wide variety of ions are available as conducting species in solids. The stage is therefore set for a massive effort at developing applications.

Solid Electrolytes: General Principles, Characterization, Materials, Applications presents specific theories and experimental methods in the field of superionic conductors. It discusses that high ionic conductivity in solids requires specific structural and energetic conditions. It addresses the problems involved in the study and use of solid electrolytes. Some of the topics covered in the book are the introduction to the theory of solid electrolytes; macroscopic evidence for liquid nature; structural models; kinetic models; crystal structures and fast ionic conduction; interstitial motion in body-centered cubic structures; and materials with the fluorite and antifluorite structures. The diffraction studies of superionic conductors are covered. The significance of defects and disorder to ionic conductivity are discussed. The text describes the transport mechanisms and lattice defects. A study of the diffusion and ionic conductivity equations is presented. A chapter is devoted to the quasi-elastic neutron scattering. Another section focuses on the complex conductivity in the microwave range. The book can provide useful information to scientists, physicists, students, and researchers.

Solid-state batteries hold the promise of providing energy storage with high volumetric and gravimetric energy densities at high power densities, yet with far less safety issues relative to those associated with conventional liquid or gel-based lithium-ion batteries. Solid-state batteries are envisioned to be useful for a broad spectrum of energy storage applications, including powering automobiles and portable electronic devices, as well as stationary storage and load-leveling of renewably generated energy. This comprehensive handbook covers a wide range of topics related to solid-state batteries, including advanced enabling characterization techniques, fundamentals of solid-state systems, novel solid electrolyte systems, interfaces, cell-level studies, and three-dimensional architectures. It is directed at physicists, chemists, materials scientists, electrochemists, electrical engineers, battery technologists, and evaluators of present and future generations of power sources. This handbook serves as a reference text providing state-of-the-art reviews on solid-state battery technologies, as well as providing insights into likely future developments in the field. It is extensively annotated with comprehensive references useful to the student and practitioners in the field.

Solid electrolytes or superionics are materials which exhibit exceptionally high values of ionic conductivity due to the rapid diffusion of one ionic species through a lattice formed by immobile counterions. Originally studied by Faraday in the 1830s, and for many years considered little more than scientific curiosities, ionically conducting solids are now a widely studied class of materials with important technological applications within solid state batteries, gas sensors and fuel cells. This book aims to provide an introduction to solid electrolytes and their historical development. A detailed summary of the major families of superionic compounds will be presented, with particular emphasis on the most important examples. An assessment of our current understanding of the relationship between the crystal structure of superionics and their bulk conduction processes will be given, permitting a discussion of the factors which promote rapid ionic motion within solids. These more 'fundamental' research issues will be complemented by a discussion of the technological applications of ionically conducting solids, their current limitations and future prospects.

This book describes the history and future views of high conductivity solid ionic conductors, ionic transport theories in solids, relations between structures and ionic transport in solid ionic and ionic electronic mixed conductors.

A hundred and eighty five chemists, physicists, and engineers met in Schenectady, New York, for the three days May 10-12, 1976, to discuss the subject of Superionic Conductors. This International Conference was held at the Research and Development Center of the General Electric Company. The subject of the Conference was fast ion transport in solids. These materials have potential application in new types of batteries, fuel cells, and sensors. Some like beta alumina are under active development in nov'el new systems. Their study has also become a popular area of scientific investigation. One objective of the Conference was to provide a forum for interdisciplinary communication between chemists, physicists, and engineers. The Conference was an attempt to bring these groups together, in order to listen to each others problems and progress. We began organizing the Conference in the spring of 1975. It was suggested to General Electric managers Drs. Craig S. Tedmon, Jr. and Roland W. Schmitt. They provided immediate and enthusiastic support. They also provided the advice, staff, and backup which were necessary at all points in the planning and duration of the Conference. We were also pleased that they could participate in the Conference: Dr. Tedmon welcomed the participants and officially opened the Conference, and Dr. Schmitt gave the after banquet address. We thank them. Additional and invaluable help, and advice, were also provided by Drs. D. Chatterji, J. B. Bush, G. W. Ludwig, and J. B. Comly. We were joined on the program committee by Drs.
