Özet

Aqueous zinc-ion capacitors (ZICs) represent a promising frontier for sustainable energy storage, however the limited capacitance and poor cycling stability of carbon-based cathodes often hinder their practical application. In this study, we report a rational design of one-dimensional (1D) porous carbon fibers (c-MDF) derived from a Mn-DHBQ metal-organic framework (MOF) precursor. Through precision-controlled coordination synthesis, a unique 1D nanowire architecture is achieved and effectively preserved during carbonization. The resulting c-MDF exhibits a remarkable specific surface area of 1236.9 m2 g−1 with a hierarchical pore structure. Electrochemical analysis demonstrates that the c-MDF cathode delivers an outstanding specific capacitance of 501.5 F g−1 at a current density of 0.1 A g−1. Kinetic analysis confirms a dominant electric double-layer capacitor-type behavior (83.1% contribution), enabling a remarkable energy density of 225.7 Wh kg−1 at a power density of 90.1 W kg−1. Most significantly, the c-MDF-based ZIC exhibits unprecedented long-term durability, maintaining a stable capacitance of 121.9 F g−1 at 2.0 A g−1 after 24,000 GCD cycles. These results highlight the synergy between 1D morphological engineering and hierarchical porosity in overcoming the kinetic bottlenecks of aqueous energy storage. This work provides a scalable and efficient pathway for developing next-generation, safe, and high-performance zinc-ion storage systems.
