Pengaruh Suhu Karbonisasi Terhadap Kinerja Elektroda Karbon Sel Superkapasitor Berbasis Cangkang Kepiting Bakau (Scylla Serrata)

---

Activated carbon is used in 80% of supercapacitor cells as an electrode material due to its high porosity, controllable porous structure, chemical stability, and high electrical conductivity. This study uses mangrove crab shells as biomass for activated carbon production with carbonization temperature variations of 600°C, 700°C, and 800°C. The carbonization aims to improve the performance of supercapacitor cells and produce high specific capacitance values. The carbon electrode from mangrove crab shells has a semicrystalline structure by the peak presence of 2θ (002) and (100) peaks at angles of 24° and 42° which contain the functional groups O-H, C-H, C=O, C-C and C-O. The carbon electrode CK-700, carbonized at 700°C, has a meso-sized pore structure and a total specific surface area of 35.037 m2/g. The atomic weight of carbon and oxygen by the CK-700 sample produced is 45.3% and 54.7%, respectively. The CK-700 sample shows a type IV isotherm with an expanding hysteresis loop, indicating an abundant mesoporous structure. The results of testing the electrochemical properties of carbon electrodes using cyclic voltammetry and galvanostatic charge-discharge methods with electrolyte used is 1 M H2SO4 produced the highest specific capacitance values in sample CK-700 of 118.84 F/g and 61.6 F/g respectively. The manufacture of carbon electrodes for supercapacitor cell applications based on mangrove crab shell biomass with a carbonization temperature of 700°C is the most optimal temperature to produce CK-700 carbon material with high electrochemical performance.
