Abstract
A molten salt electrolyte composed of lithium triflate (LiCF3SO3) and acetamide (CH3CONH2) has been prepared and characterized by Raman, IR spectroscopy and ac impedance. It is found that acetamide molecule not only complexes with the Li+ cation but also interacts with the CF3SO3â anion via hydrogen bonding due to its two polar groups (Cî
O group and NH2 group) capable of coordinating with cations and anions, respectively. Cation-anion interaction is strengthened while cation-solvent and anion-solvent interactions are weakened with the increases of salt concentration and temperature in the LiCF3SO3/acetamide complex. The ionic conductivities of the LiCF3SO3/acetamide complex with different molar ratios depend strongly on the ionic association in the complex system.
