This study explores the electrochemical properties of sucrose-derived carbon (SDC), highlighting its feasibility as a sustainable and proficient electrode material for supercapacitor applications. Sucrose, a renewable and cost-effective precursor, was carbonized through pyrolysis to synthesize porous carbon. The SDC material showed a specific surface area of 113 m 2 /g and well-developed porous structure, which facilitated efficient ion diffusion and charge storage. Electrochemical testing, including cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS), revealed that the SDC demonstrates the properties of the electrode material used in supercapacitor. The specific capacitance of SDC reached significant value 167.5 Fg −1 at lower scan rate 1 mV/s due to enhanced ion penetration into the pores, while good rate capability was observed at higher scan rates. The SDC electrode showed an excellent power density of 2979.18 Wkg −1 at energy density of 40.55 Whkg −1 , positioning it as a promising option for energy storage applications. This work highlights the potential of sucrose-derived carbon materials in sustainable energy technologies and provides a pathway for further development of high-performance, eco-friendly supercapacitors.
