Abstract:

Ionic liquid has special characteristics such as wide electrochemical windows electrochemical stability, tunable physiochemical properties etc. They are potentially excellent candidate for environmentally sound, green electrolytes in batteries. Because of its unique properties, it is essential to gain information about their dielectric properties. The Cole-Cole relaxation equation was derived and the values for the dielectric constant and loss factor of 1-ethyl-3-methylimidazolium chloride (emim) were determined. The computation was done within the frequency of 0.1GHz to 10GHz and temperature between 5⁰c to 55⁰c. The result obtained shows that the dielectric constant and loss factor of 1-ethyl-3-methylimidazolium chloride (emim) were higher at low frequency (i.e. F = 0.1GHz) and decreases as the frequency increases. The dielectric constant also increases with increase in the temperature except at 0.1GHz. The loss factor was small for all frequencies and temperatures. This may be due to the fact that the ionic liquids consumed less energy when subjected to an applied field. However it is advisable to use such IL in high frequency because the dielectric constant is low at high frequency.
