| Summary: | The present research investigates the behaviour of the limiting molar conductivity (Λo) of ENR-50/LiClO4 in a mixed solvent system comprising tetrahydrofuran (THF) and acetonitrile (ACN) at ambient temperature. The study uses the power law, to determine the Λo value of ENR-50/LiClO4/THF:ACN at a specific reference salt concentration. The ENR-50/LiClO4 electrolyte system was prepared with a fixed THF:ACN ratio of 8:2, at different ENR-50 concentration of range between 0.001-0.003 g/cm3. The correlation values obtained for the three polymer concentrations ranged from 0.9959 to 0.9966. Regression analysis revealed that as the polymer concentration increases, the Λo decreases, indicating an inverse relationship which suggesting an enhanced ion dissociation due to an increase in total free-moving ions within the liquid polymer electrolyte system. The characterization of ENR-50/LiClO4/THF:ACN was verified through ATR-FTIR spectroscopy, confirming the ion dipole interaction between the C-O-C group of ENR-50 and Li ions. © 2023 Asian Publication Corporation.
