Aqueous zinc-ion batteries(ZIBs) have attracted significant attentions because of low cost and high reliability. However, conventional ZIBs are severely limited by the development of high energy density cathode materials with reversible Zn^(2+)insertion/extraction. Herein, a conducting polymer intercalated MoO_(3)(PMO) with extensively extended interlayer spacing is developed as a high-performance ZIBs cathode material. The interlayer spacing of PMO is prominently increased which results in an improved Zn^(2+)mobility during charge and discharge process. More significantly, the electrochemical results reveals that the intercalation of PANI facilitates the charge storage and reinforces the layered structure of MoO_(3), leading to a high capacity and good cycling stability. DFT calculation further reveals the intercalation of PANI into MoO_(3)significantly lower Zn^(2+)diffusion barrier. Benefit from these advantages, the ZIBs based on PMO electrode delivers a considerable capacity of 157 m Ah/g at 0.5 A/g and ameliorative stability with 63.4%capacity retention after 1000 cycles.
