Fabrikasi Elektroda Karbon Dari Biomassa Tempurung Kemiri Dengan Variasi Suhu Aktivasi Fisika Untuk Aplikasi Sel Superkapasitor

---

Utilization of waste biomass into an economical, high-performance energy storage
device has become the focus of research in the fields of science and technology.
The high cost of production and the low storage capacity of supercapacitors are
one of the obstacles in the development of supercapacitors. In this study,
supercapacitor electrodes were synthesized from candlenut shell biomass as a
renewable carbon source by varying the physical activation temperature. The
process of making this supercapacitor cell electrode is through a pre-carbonization
process, chemical activation with 0.3 M KOH activator, chemical carbonization in
N2 gas at a temperature of 600°C and physical activation using CO2 gas with
temperature variations of 700°C, 800°C, and 900 °C. Analysis of the physical
properties of carbon electrodes showed that the sample with an activation
temperature of 800°C (TK-800) had the lowest density value of 0,805 g.cm-3 with
a shrinkage percentage of 18,62%. Microstructure analysis showed that the
sample carbon electrode TK-800 was amorphous with the lowest Lc value of
9,339 nm. The results of the FTIR analysis showed that the activated carbon of the
candlenut shell contained the functional groups O-H, C-H, C=O, and C=C.
Analysis of electrochemical properties using cyclic voltammetry and galvanostatic
charging and discharging showed that the largest specific capacitance value was
produced by sample TK-800 with specific capacitance values of 166,42 F.g-1 and
137,6 F.g-1, respectively. This study shows that the temperature of 800°C is the
optimum temperature to obtain a high capacitance value and candlenut shell
biomass which has the potential to be used as a carbon electrode for
supercapacitor cell applications
Keywords: Candlenut shell, carbon electrode, physical activation, supercapacitor.
