Structural Characterization and Electrochemical Performance of Apricot Kernel-Based Activated Carbons for Supercapacitors

Rapid industrialization and population growth have intensified global energy demands, emphasizing the need for sustainable and efficient energy storage systems. This study investigates the utilization of oil-extracted apricot kernels as a biomass precursor for activated carbon synthesis. Through carbonization and activation, two samples (ASE3 and ASE5-T) were produced and characterized using XRD, FTIR, Raman spectroscopy, SEM/EDX, BET analysis, and electrochemical testing. Among the samples, ASE3 demonstrated superior structural and electrochemical properties, highlighting its potential for energy storage applications. Structural studies revealed a micropore-dominated structure with hierarchical porosity, optimizing ion transport and charge storage. This approach provides a sustainable solution to waste management and paves the way for cost-effective alternatives to traditional energy storage materials. Future studies should explore the long-term cycling stability, the potential for industrial-scale production, and hybrid system integrations for energy storage solutions.
