The ever‐increasing demands for portable and wearable electronics continue to drive the development of high‐performance fiber‐shaped energy‐storage devices. Metal‐organic frameworks (MOFs) with well‐tunable structures and large surface areas hold great potential as precursors and templates to form porous battery materials. However, to date, there are no available reports about fabrication of wearable energy‐storage devices on the utilization of all‐MOF‐derived battery materials directly grown on current collectors. Here, MOF‐derived NiZnCoP nanosheet arrays and spindle‐like α‐Fe₂O₃ on carbon nanotube fibers are successfully fabricated with impressive electrochemical performance. Furthermore, the resulting all‐solid‐state fiber‐shape aqueous rechargeable batteries take advantage of large specific surface area and abundant reaction sites of well‐designed MOF‐derived electrode materials to yield a remarkable capacity of 0.092 mAh cm⁻² and admirable energy density of 30.61 mWh cm⁻³, as well as superior mechanical flexibility. Thus, this research may open up exciting opportunities for the development of new‐generation wearable aqueous rechargeable batteries.
