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.
