Abstract: The conductivity of pressure-elevated CO2/CH3CN/TBAPF6 mixture was determined using an AC impedance method. After adding CO2, conductivity of the pressure-elevated mixture experienced three stages: first dropping rapidly, then rising rapidly and finally slowly dropping. Based on the information obtained by the phase observation and dielectric constant determination of the CO2/CH3CN mixed solvent, the possible effect of CO2 on conductivity of the CO2/CH3CN/TBAPF6 mixture is discussed.
