Abstract
Pepper shell waste is a side effect of relatively untapped pepper production. In this research, activated carbon from pepper shell waste was made using the chemical activator ZnCl2 and followed by physical activation using nitrogen gas (N2). The resulting activated carbon is then printed into supercapacitor electrode sheets by adding carbon black, PVDF, and NMP by varying the composition between activated carbon and carbon black. The performance of the fabricated electrode sheets was then tested using the Galvanostatic Charge Discharge (GCD) method. The results show that the addition of carbon black affects the specific capacitance value of the fabricated electrode sheet. The GCD results show that the sample has a specific capacitance value of 13.64 F/g.
