  ABSTRACT: High-performance carbonaceous electrode materials for supercapacitors were synthesized by subjecting corn starch to a simple molten salt activation process with K2CO3 at a temperature of 850˚C. The resulting carbon material, obtained after activating for 1 hour, displayed excellent capacitive properties due to the synergistic effects of its porous structure. Utilizing these electrodes, the supercapacitor exhibited a high discharge capacitance (248 F g−1 at 1 A g−1), which is 2.4 times higher than that of activated carbon without K2CO3 activation. The enhancement in electrical performance was analyzed through SEM and XRD analysis, revealing that the porous and disordered structure provides a greater number of charge storage sites, resulting in improved capacitive performance.
