Solid polymer electrolyte films based on Poly(ethylene oxide) (PEO) have been prepared by solution casting technique using acetonitrile as a solvent. Succinonitrile (SN) was used as a plasticizer and lithium 4,5-dicyano-2-(trifluoromethyl)imidazole (LiTDI) as a doping salt. The following techniques such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermo gravimetric analysis, AC-impedance analysis and linear sweep voltametry have been employed to characterize the prepared solid polymer electrolyte films. The crystalline and amorphous nature of polymer electrolytes was confirmed by XRD and DSC analysis respectively. The electrolyte film with 30 wt% of SN was thermally stable up to 260°C. The ionic conductivities of polymer electrolyte films were calculated from the AC-impedance analysis. The undoped PEO 20 -LiTDI electrolyte exhibited the ionic conductivity of 9.64 9 10 -7 S cm -1 and this value was increased to 2.83 9 10 -5 S cm -1 when 30 wt% of succinonitrile was added to PEO 20 -LiTDI electrolyte at 23°C. The temperature dependent conductivity obeys Arrhenius behavior and the activation energy decreased to 0.264 eV. The electrochemical stability of the optimum conducting composition is 4.3 V, which make it attractive as electrolyte for Li battery.

“…This model is widely used for polyelectrolytes-based systems [38][39][40]. The method requires the determination of the limiting conductivities, then the calculation of ion pair and triplets conditional formation constants and finally the fractions of triplets, ion pairs and "free" ions as a function of the salt concentration [41].…”

Glycerol carbonate (4-hydroxymethyl-1,3-dioxolan-2-one, shortly GC) is a dense, viscous, water soluble solvent. The high dielectric constant and dipole moment make it a suitable non-aqueous green solvent for several salts in different applications. GC dissolves significant amounts of inorganic salts such as KF. The saturation of GC with KF leads to the formation of a viscous liquid at room temperature. In this paper, we report on conductivity, rheology, differential scanning calorimetry and infrared spectroscopy experiments that indicate the formation of a glassy liquid where GC molecules and KF ion pairs are intercalated in a firm and ordered bidimensional structure, stabilized by hydrogen bonding and strong ion-dipole interactions.
