Aqueous zinc-ion batteries (ZIBs) have attracted more attention as large-scale energy storage technology due to their high safety, low cost and environmental benignity. To date, numerous cathodes based on manganese dioxide, vanadium dioxide, and polyanionic compounds have been reported. Among them, Manganese oxides have the advantages of low cost, non-toxicity, abundant materials and high working voltage, have been widely explored as promising cathodes for zinc ion batteries. Among them, MnO₂ cathodes are particularly desirable candidates for commercialization owing to their tunnel structure and affordability. α-MnO₂has (1×1) and (2×2) tunnel structures, and Zn²⁺ can rapidly inserted and deserted in the tunnel. However, the capacity of manganese dioxide is fast decaying with the cycles due to the poor conductivity of MnO₂, which limits its electrochemical performance. Herein, α-MnO₂ nanorods are uniformly distributed on the surface of porous carbon nanosheets network (PCSs) by a simple hydrothermal/dispersion method strategy. In the α-MnO₂/PCSs architecture, the α-MnO₂ nanorods and α-MnO₂/PCSs composite were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), etc. The results testified that α-MnO₂/PCSs nanorods were firmly adhered on the surface of porous carbon nanosheets, which can effectively avoid the stacking of α-MnO₂nanorods, while the high conductive carbon network can improve the electrical conductivity of the composite. The porous network can provide effective electron transfer channels, provide stable hosts for fast Zn²⁺ extraction/insertion, and prevent the α-MnO₂nanorods from stacking each other. Benefiting from the unique porous structure and high conductive network, the α-MnO₂/PCSs hybrid shows high reversibility capacity, good rate performance, and outstanding cycling stability. Specifically, α-MnO₂/PCSs exhibits high reversible capacity of 350 mAh•g^–1 after 100 cycles at 0.1 A•g^–1 and maintains a capacity of 160 mAh•g^–1 at a high rate of 1 A•g^–1 after 1000 cycles, thus making it promising cathode for the high performance ZIBs.
