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.


"In each chapter, I like the gradual progression from the basic physics and chemistry concepts to a clear description and discussion of practical devices of current technological interest. … There is a definite need for a book of this type. Most electrochemistry books focus attention on the physical and analytical aspects of the subject. Very few books consider solid state ionics in one complete volume. … This book has the potential to be an excellent seller. The author can write and communicate complex ideas very well indeed. I would like to have a copy on my bookshelf and I would certainly use the book in my advanced courses."

—Professor Mike Lyons, School of Chemistry and CRANN, Trinity College Dublin, Ireland
