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

摘要

A new report of the synthesis of (PEO/plasticizer)LiClO_4-Li_(1.3)Al_(0.3)Ti_(1.7)(PO_4)_3 polymer electrolyte films prepared by the solution-cast technique is represented in this work. DSC trace revealed that T_g 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 firms followed Vogel-Tamman-Fulcher (VTF) equation. The pre-exponential factor (A) and the pseudo activation energy (E_a) increased with the increase of plasticizer content in the polymer electrolyte firms. At the 40 wt. percent plasticizer content, A and E_a respectively had a maximum.
