Zinc-ion　hybrid　capacitors　(ZIHC)　demonstrate　impressive　charge-storage　performance　and　intrinsic　safety　due　to　the　inherited　superiorities　of　aqueous　rechargeable　batteries　and　supercapacitors.　However,　the　promotion　of　electrochemical　performance　is　usually　hindered　by　the　cathode　materials　that　fail　to　hold　high　energy　density　and　rate　capability　of　ZIHC.　The　optimization　of　porous　carbon　cathodes　into　a　hierarchical　structure　is　an　efficient　strategy　to　break　the　bottlenecks　of　ZIHC.　Herein,　a　metal　oxide　space-confined　strategy　is　proposed　to　build　3D　graphene-like　porous　carbon　nanosheets　(3DPC)　with　doping　of　O　and　S　heteroatoms　by　using　low-cost　aromatic　hydrocarbons　as　precursors.　It　is　found　that　the　obtained　3DPC　consists　of　micro-,　mseo-　and　macropores　and　further　delivers　a　high　specific　surface　area　of　2813　m2　g−1　with　a　total　pore　volume　of　1.82　cm3　g−1.　Specifically,　such　a　well-defined　hierarchical　porosity　of　3DPC　coupled　with　rich　O　and　S　heteroatoms　enables　sufficient　multilevel　ion　transport　channels　and　large　accessible　surface　sites　to　capture　the　Zn2+　ions.　As　a　proof　of　concept　demonstration,　the　assembled　aqueous　ZIHC　by　employing　the　3DPC　cathode　exhibits　a　desirable　capacity　of　194　mAh　g−1　at　0.5　A　g−1　with　a　superior　rate　capability　of　53%　at　30　A　g−1　and　excellent　cycling　stability　of　over　88%　after　15000　cycles.　Moreover,　the　remarkable　electrochemical　performance　of　the　3DPC　cathode　can　be　well-preserved　in　the　case　of　a　quasi-solid-state　ZIHC　device　under　various　harsh　bent　states,　highlighting　the　promising　application　in　flexible　and　wearable　energy　storage.　©　2022　Elsevier　Ltd
