Abstract Low‐cost and high‐loading cathodes are crucial for practical application of zinc‐ion supercapacitors (ZICs) but achieving optimal performance in electrodes faces challenges due to sluggish ion transport, increased resistance, unstable structure. Guided by theoretical calculations, carbon based on holey activated sheets (HACS) fabricated from a carefully chosen molecule. A simple pyrolysis‐leaching treatment transformed the molecule into HACS with large surface area, hierarchical porous structure, electroactive oxygen/nitrogen dopants. When combined an aqueous binder, optimized HACS‐based electrode (16.1 mg cm −2 ) exhibits high‐capacitance (454 F g −1 fast‐rate (1 characteristics under lean electrolyte (6.2 µL ). More impressively, is dry‐pressed free‐standing thick up 35.4 corresponding ZIC limited Zn low N/P ratio demonstrates ultrahigh areal capacitance (9 energy density (3.47 mWh The outstanding can be attributed fast transport enabled through‐plane pores HACS, as well abundant double‐layer redox‐active surfaces favorable heteroatom‐doped nanosheets. With its cost‐effectiveness, elemental abundance, structural tunability, this molecular strategy offers platform making self‐activated at level towards supercapacitors.
