Abstract: Supercapacitive properties of electrodes built from ionic liquid-Multi Walled carbon Nanotubes (MWNTs) gel electrodes have been investigated. IL/MWNTs gel was easily prepared by adding MWNTs into 1-methyl-3-octadecylimidazolium bromide ionic liquid aqueous solution, then the resulting gel deposited on Nickel foam by Electrophoretic deposition. Electrochemical characterizations were carried out by cyclicvoltammetery and impedance spectroscopy in 1M KOH aqueous solution at room temperature. The specific capacitance of this electrode (120 F/gr) was larger than those were reported for bare carbon nanotube electrodes, and pseudo faradic reactions have been detected.
