Abstract

We propose a novel idea to utilize environment pollutant cigarette ash for energy storage material as electrode of supercapacitors as supercapacitors can deliver high power and reasonable energy densities as compared to batteries which deliver energy as a result of chemical reactions and suffer with low power densities. Keeping in view this advantage and research focus in this field, supercapacitors of cigarette ash were fabricated as energy storage devices. The electrode composed of ash shows specific capacitance of 183.33 F/g at current density of 1 A/g for 1st cycle and 165 F/g for 2000th cycle which indicate its remarkable long-term cyclic stability in Na2SO4 electrolyte.
