Potensi Daun Belimbing Wuluh (Averrhoa Bilimbi L.) Sebagai Sumber Karbon Aktif Untuk Elektroda Superkapasitor

---

The potential of Averrhoa bilimbi leaves as activated carbon-based
material for supercapacitor electrodes has been successfully carried out through
chemical activation at high temperature pyrolysis. Chemical activation of KOH
was applied in three concentration variations including 0.3 M, 0.5 M and 0.7 M.
The fabrication of carbon electrodes from Averrhoa bilimbi leaves was prepared
in several stages such as drying in the sun, drying using an oven, precarbonization,
chemical activation, pellet printing using a hydraulic press. The
pellets that have been molded were then carbonized using N2 gas at a temperature
of 600°C and physically activated using CO2 gas at a temperature of 800°C. The
activated carbon obtained shows a 3D hierarchical connected pore structure. In
addition, activated carbon has produced a high carbon content of 87.22% with
clearly confirmed amorphous phase. The electrochemical properties of the
supercapacitor cells were reviewed through a two-electrode system in aqueous
electrolyte 1 M H2SO4. The optimum activated carbon sample obtained is DB 0.5
which confirmed a high specific capacitance reaching 263 F/g at a current density
of 1.0 A/g. In addition, the maximum energy density obtained is 26.54 Wh/kg at
the optimum power density of 173.14 W/kg. These results clearly demonstrate the
great potential of Averrhoa bilimbi leaves as a source of activated carbon with a
3D hierarchical pore structure to improve the performance of supercapacitor
electrochemical energy storage devices.
Keywords : Averrhoa bilimbi leaves, supercapacitors, carbon electrodes, specific
