Sintesis Elektroda Karbon Dari Limbah Biomassa Serabut Palem Putri Untuk Aplikasi Sel Superkapasitor

---

Supercapacitors are renewable energy storage devices consisting of electrodes,
electrolytes, current collectors, and separators. Electrodes are one of the most
important components in supercapacitors because they are made of nanoscale
materials that have high surface area and porosity. In this study, carbon electrodes
were made from palm fiber biomass waste with variations in the physical
activation temperature of 650 , 700 , and 750 with the sample codes being
SPP-650, SPP-700, and SPP-750, respectively. The fabrication of carbon
electrodes was carried out by several processes, namely the pre-carbonization
process, chemical activation with KOH activator, carbonization process using N2
gas at a temperature of 600 and physical activation using CO2 gas. Thermal
analysis using TGA resulted in mass reduction at a temperature of 288,9 with a
maximum speed of 0,903 mg/min. The highest density value of the samples is
found on the carbon electrode with a sample code of SPP-700 with a mass loss
percentage value of 31,52%. Microstructure analysis of SPP carbon electrodes
showed an amorphous structure with two broad peaks at 2θ angles around 26⁰
and 44⁰ angles corresponding to the (002) and (100) planes, where the highest Lc
and the lowest La were owned by SPP-700 with respective values 16,007 nm and
13,017 nm. The chemical element content analyzed using Energy Dispersive XRay
(EDX) has the element Carbon (C) with the highest atomic percentage of
92,83% which is owned by the SPP-700 sample. Electrochemical characterization
using Cyclic Voltammetry (CV) showed that the SPP-700 supercapacitor cell
produces the highest specific capacitance value of 231,108 F/g. The temperature
of 700 is the best temperature in the synthesis of activated carbon electrodes
from palm fiber biomass which can improve the performance of supercapacitor
cells.
