Biomass-derived energy storage devices are emerging as a sustainable strategy to reduce reliance on nonrenewable resources. Herein, wheat husk-derived active-carbon coated CoP nanostructures (CoP@NWHC) were synthesized for the first time via facile treatment followed by hydrothermal growth. In the CoP@NWHC composite, carbon nanostructures are conformally grown on both the interior and exterior surfaces of the CoP framework. This integrated carbon layer not only provides structural support for CoP but also establishes continuous conductive pathways that facilitate rapid electron transport throughout the electrode. Furthermore, the hollow helical carbon structure with inherent capillary effects provides rapid ion diffusion channels. Owing to this hierarchical architecture, the CoP@NWHC electrode delivers a high specific capacitance of 521 F g⁻¹ at 0.5A g⁻¹, excellent cycling stability of 90.4% after 8000 cycles. Demonstrating its potential for practical energy storage applications.
