The thermodynamic parameters of activation of viscous flow of solutions butylene carbonate (BuC), pentylene carbonate (PeC), and hexylene carbonate (HeC) were obtained with high yield (> 95%). were studied at -45 and 25°. Propylene carbonate (PC) has also been used as a solvent/co-solvent to prepare electrolyte solutions for these energy storage devices. The results were discussed in terms of intermolecular interactions. The value at 25°C supports the value at 20°C. versus the ILs concentration exhibited a change in the medium structure. The temperature dependence of both the viscosity and conductivity of each mixture exhibits a non-Arrhenius behaviour, but is correctly fitted by using the Vogel–Tamman–Fulcher (VTF) equation. The activation parameters have been evaluated using the transition-state treatments of Eyring and Feakins. All rights reserved.
