Abstract

The electrochemical performance of the organic electrolytes based on ramifications of 2-oxazolidinone containing different lithium salts are studied with AC impedance spectroscopy. The quantum chemistry calculations with nonlocal density function theory (DFT) indicated that the substitution group of organic molecules influences the ionic conductivity of electrolyte. Of all the electrolytes, 0.75 mol/L LiPF₆/N-ethylene-4-methyl-2-oxazolidinone(EMOZO) shows the highest ionic conductivity, 3.05 × 10^-3 S/cm at 25°C and 9.73 × 10^-3 S/cm at 80°C. In order to evaluate the performance of the electrolyte in practical electrochemical devices, an electric double layer capacitor is assembled with 0.75 mol/L LiPF₆/EMOZO. The experiments show that the capacitor has the typical capacitance characteristics and good reversibility and cycle ability.
