Objective: This paper studies the effects of lithium trifluoroacetate (CF3 COOLi) when used in a Polyvinylidene fluoride (PVDF) membrane to improve its ionic conductivity for use as electrolyte for electrochemical devices. Method: CF3 COOLi/PVDF Ionic conductive membranes have been prepared by solution method. The samples were characterized by impedance spectroscopy (IS) with temperatures ranging from 298 K at 373 K. Results: The plots of conductivity with the inverse of temperature show an Vogel-Tamman-Fulcher (VTF) behavior, with pseudo activation energies between 7.30 × 10-3 y 5.05 × 10-4 eV. Conclusions: The higther conductivity (3.848 × 10-4 S cm-1) was obtain at room temperature to higth concentration of CF3 COOLi, this values is similarity with results from other documents.
