Addition of reduced graphene oxide to carbon shaft based on cerbera manghas mesocarp to improve energy storage performance of supercapacitor cells
DIAMOND AND RELATED MATERIALS(2024)
Abstract
Improving the electrochemical performance of biomass-based porous carbon materials has been widely studied, one of which is by adding other materials such as rGO. In this work, a porous carbon based on cerbera manghas mesocarp biomass with the addition of rGO (CMG) has been successfully synthesized. The mass addition of rGO was varied to determine how it affects capacitive performance. CMG samples were characterized using SEM, EDX, XRD, FTIR, and BET. The morphology obtained has an abundant pore structure so that there are many paths through which ions can diffuse, is rich in C content and has a large surface area. Electrochemical performance measurements in a two-electrode system revealed that CMG-03 had the largest specific surface area (787.574 m2 g-1) and the highest specific capacitance (286 F g-1 at 1 mV s-1). The results obtained can provide information that cerbera manghas mesocarp biomass with the addition of rGO has the potential to be used in supercapacitor applications.
