Conductivity studies of plasticized PEO-Lithium chlorate–FIC filler composite polymer electrolytes

Abstract A new report of the synthesis of (PEO/plasticizer)LiClO4–Li1.3Al0.3Ti1.7(PO4)3 polymer electrolyte films prepared by the solution-cast technique is represented in this work. DSC trace revealed that Tg decreased with the increase of plasticizer content in the polymer electrolyte films. SEM morphology showed that the surface morphology of films was relatively smooth and homogeneous. Conductivity studies by EIS measurement indicated that the temperature dependence of ionic conductivity of films followed Vogel–Tamman–Fulcher (VTF) equation. The pre-exponential factor (A) and the pseudo activation energy (Ea) increased with the increase of plasticizer content in the polymer electrolyte films. At the 40 wt.% plasticizer content, A and Ea respectively had a maximum.
