Some Problems in the Theory of Solid Electrolytes

Modem theoretical views on solid electrolytes (i.e. solids whose ionic conductivity is anomalously high) are reviewed, and various mechanisms for the creation of disorder in one of the ionic sublattices are analysed, together with schemes for the phase transitions to the superionic state and with the dependence of the characteristics of these transitions on the parameters of the crystal and on the charge transfer phenomena in the solid electrolyte. Problems in the microscopic description of ionic transport in solid electrolytes are examined, and the theoretical foundations of the experimental methods used to study the properties of solid electrolytes are discussed. 243 references.
