Supercapacitors are energy storage devices consisting of electrodes, electrolyte,
current collectors, and separator. Supercapacitor cells have components called
electrodes. In this study, the basic material used to make supercapacitor cell
electrodes is young cocofiber with varians temperature of physical activation i.e.
700oC, 750oC and 800oC. The process of preparation supercapacitor cell
electrodes begins with pre-carbonization using an electric oven, chemical
activation using 0.5M KOH activator, and carbonization process using N2 gas at a
temperature of 600oC and physical activation using CO2 gas. The highest density
value is owned by the SKM-750 sample with a density loss percentage value of
41.38%. The X-ray diffraction pattern indicates that the samples have a
semicrystalline structure, indicated by the presence of a gently sloping peak at 2θ
around 22o and 44o. Analysis of the physical properties of supercapacitor cell
electrodes made from young coconut fiber showed that the sample with a physical
activation temperature of 750oC was the better sample, indicated by an Lc/La ratio
of 0.87 with an average number of microcrystalline inner layers 2.15, a pore
diameter of 23.90 nm and the percentage of Carbon content in the sample is
94.19%. Analysis of electrochemical properties showed that the sample with a
temperature of 750oC was the sample with the highest specific capacitance value,
namely, 236.7231 F/g in the CV test and 321.4694 F/g in the GCD test.
Keywords: Young cocofiber, Activated Carbon electrode, Physical activation
