Effect of nano-filler on the performance of multiwalled carbon nanotubes based electrochemical double layer capacitors
This article presents the main features of electrochemical double layer capacitor (EDLC), made up of multiwalled carbon nanotubes as electrode materials and electrolyte based on nano silica dispersed in poly(vinylidene fluoride-co-hexafluoropropylene)-based magnesium ion conducting nano composite gel polymer electrolyte. The capacitance value was stable up to 5000 voltammetric cycles and even more. The performance characteristics of EDLC have been tested using cyclic-voltammetry, impedance spectroscopy, and charge-discharge techniques. Analysis shows that the nano-filler based EDLC has relatively larger capacitance value as compared to filler-free based electrolyte. The maximum capacitance of 92 mF cm−2, equivalent to single electrode specific capacitance of 92 F g−1 was achieved. It corresponds to energy-density of 10.5 W h kg−1 and power-density of 3.25 kW kg−1.
