Electroactive organic-based compounds have garnered considerable attention as an emerging candidate to replace inorganic counterparts by providing safety, lightweight, and molecular diversity. Yet, their low energy and power densities often impose a critical impediment for practical applications. Herein, we unveil that all-fibrous heteromat framework comprising intermingled polyacrylonitrile nanofibers and carbon nanotubes can offer three-dimensional bicontinuous electron/ion conductive pathways toward organic active materials, along with good mechanical flexibility. Nickel 2,6-naphthalenedicarboxylate (NiNDC) is explored as a model organic anode material for this electrode strategy. Driven by the structural uniqueness, the self-standing heteromat NiNDC anode ultimately affords facile redox kinetics and exceptionally high electrochemical performance, which lie far beyond those achievable with conventional lithium-ion battery organic-based anodes. |
