Abstract

In this study, liquid electrolyte samples were prepared where each of the samples contained a constant amount of dimethylformamide (DMF) but different concentration of zinc triflate (ZnTf). The ionic conductivity of each sample then was tested by using the impedance spectroscopy technique. A sample that had the optimum value of ionic conductivity was selected to be used in the preparation of polymer gel electrolyte. The optimum value of ionic conductivity of the liquid electrolyte sample was 4.03 x 10⁻ᶾ Scm"1 and obtained from the sample of 0.5M of ZnTf -DMF. Next, polymer gel electrolyte samples containing the 0.5M of ZnTf + DMF and different weight% of poly (vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) were prepared. The ionic conductivity of each sample was tested by using the impedance spectroscopy technique. The highest ionic conductivity was 1.50 x 10⁻² Scm⁻¹ and obtained from the sample of 0.5M of ZnTf-DMF-6wt. % of PVDF-HFP. It was then used in the battery fabrication.
