Incorporation of IL in PGEMs increases the amorphicity of the membranes, through reducing the intermolecular interaction between the polymer chains, and also increases the membrane ionic conductivity.

Figure (a) shows that the semi-crystalline nature of the polymer PVdF-HFP and Figure (b) shows that the polymer chain became flexible on the addition of LiTFSI salt. Furthermore, on the addition of IL in polymer electrolyte membranes, the membranes became more flexible and provide high ionic conduction (because of more availability of ions) in the system resulting in enhancement of the ionic conductivity (see Figure (c)).

AbstractIn the present studies, the effect of ionic liquid 1-Ethyl-2,3-dimethylimidazoliumtetrafluoroborate (EDiMIM)(BF4) on ionic conductivity of gel polymer electrolyte using poly(vinylidene fluoride-co-hexafluoropropylene) [PVdF(HFP)] and magnesium perchlorate [Mg(ClO4)2] as salt was investigated. The maximum room temperature ionic conductivity for the optimized system was found to be of the order of 8.4 × 10–3 S cm−1. The optimized composition reflects Vogel-Tammann-Fulcher (VTF) behavior in the temperature range of 25 °C to 100 °C. The X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy studies confirm the uniform blending of ionic liquid, polymer, and salts along with the enhanced amorphous nature of the optimized system. Dielectric and modulus spectra studies provide the information of electrode polarization as well as dipole relaxation properties of polymeric materials. The optimized electrolyte system possesses a sufficiently large electrochemical window of the order of 6.0 V with stainless steel electrodes.
