Electrical Conductivity of 1-Butyl-3-Methylimidazolium Chloride (BMIC) and Aluminum Chloride (AlCl3) Ionic Liquid Electrolytes: Aninda Nafis Ahmed1; Md Khalid Nahian1; Ramana Reddy1; 1University of Alabama Tuscaloosa
Conductivity of aluminum chloride (AlCl3) and 1-butyl-3-methylimidazolium chloride (BMIC) system was studied as a function of temperature and AlCl3 molar ratio by electrochemical impedance spectroscopy (EIS). The temperature was varied from 70oC to 110oC. Composition of ionic liquid was varied by changing the molar ratios of BMIC:AlCl3 of 1:1.5, 1:1.8 and 1:2. It was found that the conductivity increases with temperature and decreases with ratio and increase in the AlCl3 in the electrolyte. The conductivity data followed Arrhenius law from which activation energies for each molar ratio were calculated. The BMIC:AlCl3 ratio of 1:2 has lowest activation energy (14.73kJ/mol) and lowest conductivity. Statistical analysis was done by ANOVA on the experimentally obtained conductivity data. Both the molar ratio and the temperature of the ionic liquid electrolyte are critical to achieve good electrical conductivity.
