ABSTRACT This study introduces a novel composite cathode for aqueous zinc‐ion batteries (ZIBs), leveraging porous basil‐derived activated carbon (BAC) and nanostructured manganese dioxide (MnO 2 ) synthesized through one‐step hydrothermal process. For the first time, is integrated with MnO , resulting in enhanced electrochemical performance. The /BAC delivers remarkable specific capacity of 237 mAh/g at 0.5 A/g, along an energy density 314 Wh/kg power 0.66 kW/kg, outperforming cathodes made from pristine or BAC. These improvements stem reduced particle size synergistic balance capacitive diffusive charge storage mechanisms. Density functional theory calculations corroborate experimental results, revealing composite's superior quantum (158.7 µC/cm capacitance (80.4 µF/cm ). Stability assessments highlight excellent cycle life, > 90% retention 100% Coulombic efficiency over 300 cycles. exceptional performance attributed to material's unique nanostructure, high surface area (1090 m /g), optimized porosity. Additionally, practical applications ZIBs pouch cell form using MnO₂/BAC are demonstrated, showcasing its capability toy car satisfactory distance. establishes new benchmark sustainable cost‐effective materials, significantly advancing ZIB technology high‐efficiency applications.
