Two-dimensional conductive metal-organic frameworks (2D CMOFs) can be regarded as high-performance electrode substances owing to their rich hierarchical porous architecture and excellent electrical conductivity. However, the sluggish kinetics behavior of electrodes within bulk structure restricts advances in energy storage fields. Herein, a series graphene-based mixed-dimensional composite aerogels are achieved by incorporating 2D M-tetrahydroxy-1,4-quinone (M-THQ) (M = Cu, Cu/Co, or Cu/Ni) into CNTs@rGO aerogel using 3D-printing direct ink writing (DIW) technique. Benefiting from high capacity M-THQ abundant porosity 3D-printed microlattice electrodes, an capacitive performance M-THQ@CNTs@rGO cathodes is based on fast electron/ion transport. Furthermore, lithium-ion hybrid supercapacitor (LIHCs) device assembled with Cu/Co-THQ@CNTs@rGO cathode C60@VNNWs@rGO anode delivers remarkable electrochemical performance. More importantly, this work manifests practicability printing CMOFs which provides substantial research basis for 3D storage.
