Abstract

Supercapacitor offers high energy density, stability and can be build using environment-friendly material. To deepen understanding on how supercapacitor material effect its properties, this work study the effect of treatment on every component of supercapacitor. The capacitor is composed by electrodes, current collector, separator and aqueous electrolyte. The electrode made from activated carbon (AC) and mixture of activated carbon with carbon nanotube (CNT). Before applying to current collector AC and CNT is heat treated in 800°C for an hour for AC and 650°C for 30 minutes for CNT. The current collector treated with cleaning, sanding and applying conductive paint. After treatment has given, capacitor then assembled and 6M KOH of electrolyte added. Supercapacitor then analyzed and characterized using constant current discharge (CCD) technique. The characterization result showed that there is decrement in supercapacitor internal resistance and heat treatment on electrode material improves capacitance of supercapacitor when compared to the untreated one.
