Synthesis activated carbon of pepper peel as supercapacitor electrodes

Abstract

The Supercapacitor electrodes made from activated carbon from biomass waste have attracted researchers’ interest as an energy storage medium. Activated carbon was synthesized from pepper peel waste with 1 M ZnCl2 activator and an activation temperature of 700°C Meanwhile, the supercapacitor electrodes were prepared using activated carbon which had been synthesized by adding acetylene black (AB) and polyvinyl de fluoride (PVDF) materials to make a homogeneous mixture. Then the sample is printed and dried using an oven. The electrode samples were then tested using SEM-EDX and CV to characterization of their morphology and energy storage capability. The CV results show that the sample has a specific capacitance value of 17.4 F/g.
