Solid Electrolytes For Advanced Applications

This book highlights the state of the art in solid electrolytes, with particular emphasis on lithium garnets, electrolyte-electrode interfaces and all-solid-state batteries based on lithium garnets. Written by an international group of renowned experts, the book addresses how garnet-type solid electrolytes are contributing to the development of safe high energy density Li batteries. Unlike the flammable organic liquid electrolyte used in existing rechargeable Li batteries, garnet-type solid electrolytes are intrinsically chemically stable in contact with metallic lithium and potential positive electrodes, while offering reasonable Li conductivity. The book's respective chapters cover a broad spectrum of topics related to solid electrolytes, including interfacial engineering to resolve the electrolyte-electrode interfaces, the latest developments in the processing of thin and ultrathin lithium garnet membranes, and fabrication strategies for the high-performance solid-state batteries.This highly informative and intriguing book will appeal to postgraduate students and researchers at academic and industrial laboratories with an interest in the advancement of high energy-density lithium metal batteries

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.

Explains the current state of the science and points the way to technological advances First developed in the late 1980s, lithium-ion batteries now power everything from tablet computers to power tools to electric cars. Despite tremendous progress in the last two decades in the engineering and manufacturing of lithium-ion batteries, they are currently unable to meet the energy and power demands of many new and emerging devices. This book sets the stage for the development of a new generation of higher-energy density, rechargeable lithium-ion batteries by advancing battery chemistry and identifying new electrode and electrolyte materials. The first chapter of Lithium Batteries sets the foundation for the rest of the book with a brief account of the history of lithium-ion battery development. Next, the book covers such topics as: Advanced organic and ionic liquid electrolytes for battery applications Advanced cathode materials for lithium-ion batteries Metal fluorosulphates capable of doubling the energy density of lithium-ion batteries Efforts to develop lithium-air batteries Alternative anode rechargeable batteries such as magnesium and sodium anode systems Each of the sixteen chapters has been contributed by one or more leading experts in electrochemistry and lithium battery technology. Their contributions are based on the latest published findings as well as their own firsthand laboratory experience. Figures throughout the book help readers understand the concepts underlying the latest efforts to advance the science of batteries and develop new materials. Readers will also find a bibliography at the end of each chapter to facilitate further research into individual topics. Lithium Batteries provides electrochemistry students and researchers with a snapshot of current efforts to improve battery performance as well as the tools needed to advance their own research efforts.

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.
