| 英文摘要 | In this paper, the incorporation of a highly conductive material (polypyrrole) into a binary metal-oxide core-shell structured composite is adopted to optimize the charge transfer process to further improve electrochemical performance. Because of enhanced electron transfer capability, charge transfer resistances of the ternary core-shell structured composites are reduced and the electrochemical performances are improved. For example, the Co3O4@PPy@MnO2 ternary core-shell heterostructured composite exhibits high specific capacitance and excellent rate capability (53% of capacity retention rate at 40 A g(-1) compared with 782 F g(-1) at 0.5 A g(-1)). The composite shows good cycling stability with 97.6% capacity retention over 2000 cycles at 5 A g(-1). These results demonstrate the potential of core-shell composites to further improve the performance in supercapacitor electrodes. |
