Sintesis Dan Karakterisasi Karbon Aktif Berbasis Serabut Kelapa Muda Sebagai …

ABSTRACT Supercapacitor is energy storage devices consisting of electrodes, electrolyte, current collectors, and separator. In this research, carbon electrodes are made from young coconut fiber biomass (SKM) waste using ZnCl2 0.5 M as activation agent and variations in physical activation temperatures. Carbon electrodes preparation begins with a pre-carbonized process of 200oC temperatures for…
