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.eninfo:eu-repo/semantics/openAccessEnergy-StoragePorous CarbonBiomassElectrodesShellArticle103134254342654082155710.1021/acsomega.5c009192-s2.0-105013669805Q1WOS:001540562500001Q20000-0003-4321-8264
