Abstract The rise of Zn‐ion hybrid capacitor (ZHC) has imposed high requirements on carbon cathodes, including reasonable configuration, specific surface area, multiscale pores, and abundant defects. To achieve this objective, a template‐oriented strategy coupled with multi‐heteroatom modification is proposed to precisely synthesize three‐dimensional boron/nitrogen‐rich nanoflake‐interconnected micro/nano superstructure, referred as BNPC. hierarchically porous framework BNPC shares short channels for fast Zn 2+ transport, increased adsorption‐site accessibility, structural robustness. Additionally, the boron/nitrogen incorporation effect significantly augments adsorption capability more distinctive pseudocapacitive nature, notably enhancing storage transmission kinetics by performing dual‐storage mechanism electric double‐layer capacitance Faradaic redox process in cathode. These merits contribute capacity (143.7 mAh g −1 at 0.2 A ) excellent rate (84.5 30 BNPC‐based aqueous ZHC, ZHC still shows an ultrahigh 108.5 even under mass loading 12 mg cm −2 . More critically, flexible device also sustains notable cyclability over 30,000 cycles low‐rate self‐discharge 2.13 mV h along preeminent energy output 117.15 Wh kg power density 163.15 W , favoring creditable applicability modern electronics. In/ex‐situ analysis theoretical calculations elaborately elucidate enhanced charge depth. findings offer promising platform development advanced cathodes corresponding electrochemical devices.
