Abstract While MXene is widely used as an electrode material for supercapacitor, the intrinsic limitation of stacking caused by interlayer van der Waals forces has yet to be overcome. In this work, a strategy proposed fabricate composite scaffold (MCN) intercalating with highly nitrogen‐doped carbon nanosheets (CN). The 2D structured CN, thermally converted and pickling from Zn‐hexamine (Zn‐HMT), serves spacer that effectively prevents contributes hierarchically scaffolded structure, which conducive ion movement; meanwhile, high nitrogen‐doping CN tunes electronic structure MCN facilitate charge transfer providing additional pseudocapacitance. As result, MCN50 achieves specific capacitance 418.4 F g −1 at 1 A . assembled symmetric supercapacitor delivers corresponding power density 1658.9 W kg energy 30.8 Wh all‐solid‐state zinc demonstrates superior 68.4 403.5 shows retention 93% after 8000 charge‐discharge cycles. This study sheds new light on design development novel MXene‐based electrodes performance supercapacitor.
