This paper describes the preparation and characterization of lithium fluoroalkylphosphate-containing composite polymer electrolyte based on a polyvinylidene fluoride–hexafluoropropylene (PVdF–HFP) matrix. A mixture of ethylene carbonate and diethyl carbonate was used as a plasticizing agent and nanoscopic Al2O3 as a filler. The membranes were characterized by ac impedance, SEM, DSC, FTIR and fluorescence. An electrolyte with 2.5 wt% Al2O3 exhibited a conductivity of 9.8 104 S cm1 at ambient temperature. It was found that filler contents above 2.5 wt% rendered the membranes less conducting.
