High Capacitance Nitric Acid-Functionalized MWCNT/PANI composite Supercapacitors under operando conditions

Abstract

Nowadays, being able to store and recover energy quickly is becoming increasingly more important for different applications. This Study report on novel electrode material composed of MWCNTs directly synthesized over a fine aluminum foil in CVD then functionalized with Nitric Acid and placed in Coin cells. The electrolyte used was an aqueous solution of Lithium Sulfate 1Mol/L with Sonicator-scattered Pani. This Material showed a good lifetime, solid electric potential stability until 2V and improved Capacitance going up to 135 F g-1 demonstrating the feasibility of this composite and the techniques involved in near future's State-of-Art supercapacitors.
