Fluorinated Hexa-Peri-Hexabenzocoronene Derivatives-Modified CNT Scaffolds Enabling Ultrahigh Capacitance in Hierarchical NiCu-LDH Hybrid Supercapacitors.

ABSTRACT: Achieving high capacitance while maintaining rapid charge transport and structural stability remains a major challenge in the design of battery-type supercapacitor electrodes. Herein, a molecularly engineered strategy is presented for constructing hierarchical hybrid electrodes by integrating petal-like NiCu-LDH nanosheets onto 3D HBC-x (x = H, F, OMe)-functionalized CNT paper via a one-step hydrothermal process. The incorporation of HBC effectively mitigates CNT agglomeration and constructs an interconnected conductive framework that enhances charge transport, shortens ion diffusion paths, and reduces internal resistance. Among the variants, fluorinated HBC-F offers the most pronounced performance improvement, owing to the formation of polar semi-ionic C-F bonds that elevate local charge
