摘要：

The Meyer-Neldel rule is applied to describe the relation between the pre-exponential factors sigma0 and activation energies of various blend-based and composite polymeric electrolytes for which the temperature dependence of the conductivity satisfies the Arrhenius law. It is shown that for these electrolytes changes of ionic conductivity come from the variation of the migration entropy term. The correlations between the entropy of ion migration, phase structure and phase transitions are discussed. The physical meaning of the temperature T(D) calculated from the Meyer-Neldel equation is proposed.
