Pengaruh Variasi Suhu Karbonisasi Terhadap Elektroda Karbon Dari Biomassa Pelepah Salak Untuk Aplikasi Superkapasitor

---

Supercapacitors are energy storage devices that have many advantages, including
quick charging and an unlimited lifespan. This research aims to determine the
potential of snake fruit midrib biomass (PS) as a precursor material for making
carbon electrodes for supercapacitor cell application. Carbon electrodes were
made from snake fruit midrib biomass using a pre-carbonization process at 200°C
for 1 hour, chemical activation with 0.1 M KOH as an activating agent, a
carbonization process with temperature variations of 500°C, 600°C, 700°C, and
750°C using N2 gas, and a physical activation process at 800°C with CO2 gas. The
sample mass experienced a mass shrinkage of 21.5%. Thermogravimetric analysis
shows the thermal resistance temperature of carbon powder is 317.1 ˚C. The
density values of the samples PS-500, PS-600, PS 700, and PS-750 were 0.862
g/cm3, 0.759 g/cm3, 0.747 g/cm3, and 0,953 g/cm3. Microstructure analysis found
that carbon electrode is semi-crystalline marked by peaks (002) and (100) at 2
angles around 22˚ and 44˚. Specific capacitance values were determined using the
cyclic voltammetry method for PS-500, PS-600, PS-700, and samples obtained
values are 171.73 F/g, 191.04 F/g, 241.51 F/g, and 125,01 F/g. According to these
results, the best carbonization temperature for carbon electrodes made from snake
fruit midrib biomass is 700°C.
