AB - Electric double-layer capacitors (EDLCs) have attracted significant interest as a promising energy storage solution because of their high-power density, exceptional charge/discharge cycle stability, and extended lifespan. Porous carbon is a key component of EDLCs given its outstanding chemical stability, high electrical conductivity, large specific surface area, and cost effectiveness. We fabricated porous carbon from oak wood as a raw material using an environment-friendly steam activation process (physical activation). Pretreatment (stabilization) was conducted using a mild acid (phosphoric acid) to achieve a high specific surface area and maintain structural stability. Oak wood-derived porous carbon (Oak-PC) produced with varying activation times following phosphate stabilization achieved high specific surface area (1050–1990 m2/g), pore volume (0.44–0.95 cm3/g), and carbonization yield (36%). Oak-PC retained ~ 90% of its performance at a high current density (10 A/g), demonstrating superior EDLC performance compared to that of commercial porous carbon. These results were attributed to the significant enhancement of the electrical properties of Oak-PCs, achieved by removing char through phosphate stabilization and strengthening bond stability. This study provides foundational data for developing sustainable energy storage technologies and enhancing the efficiency of next-generation energy storage systems by utilizing environment-friendly biomass materials such as oak wood.
