The aqueous-based zinc-ion batteries (ZIBs) with higher safety and performance have gained great attention from scientists. Nevertheless, previous electrode materials mainly rely on inorganic metal oxides, and their structure is prone to collapse during charge and discharge, thus resulting in poor cycle stability, which severely limits the development of ZIBs. Here, a novel conjugated polyimide based conjugated microporous polymer (CMP) and multi-walled carbon nanotubes (CNT) hybrid has been gained and used as cathode material for ZIBs. The aromatic carbonyl group as active site can reversibly receive and release zinc ions, thus showing good electrochemical performance. This work provides new view for the design of high-performance ZIBs electrode materials.
