1-Methyl-3-butylimidazolium tetraflouroborate with activated carbon for electrochemical double layer supercapacitors
چکیده انگلیسی

This article presents the main features of electrochemical double layer supercapacitors, made of nanostructured carbon materials with specially selected and optimized porosity structure and electrolyte based on solvent-free ionic liquid as follows 1-methyl-3-butylimidazolium tetrafluoroborate (1Me3BuImBF4). The performance of supercapacitor was carried out by cyclic voltammetry and galvanostatic charge/discharge measurements. The main characteristics of stacked supercapacitors exhibit a nominal voltage 3.0 V and a maximum cell voltage 3.5 V as well as a specific capacitance (individual electrode of supercapacitor) of 111 F/g. The specific energy of 4.1 Wh/kg and specific power of 1.7 W/kg for industrial stacked supercapacitor has been achieved.
