摘要：

The universal power law describing the relation between dc and ac conductivities is applied to the data obtained for various polymeric electrolytes. Changes of activation energy of conduction, hopping rate, activation energy for ion hopping and activation energy of charge carriers creation are analyzed according to the West-Almond formalism. The obtained results are correlated with the phase structure of the polymeric electrolyte and its ambient temperature ionic conductivity. We find that high conductivity values are measured for systems for which the activation energy of ion hopping is considerably lower compared to the activation energy of charge carrier's creation.
