英文摘要advantages in terms of high safety, low cost, and environmental friendliness. However, the lack of suitable cathodes with highcapacity, long-cycling, and high-rate capability limits their practical application. Herein, we present a highly crystalline onedimensional 2r-d conjugated conductive metal-organic framework by coordinating ultrasmall 1,2,4,5-benzenetetramine (BTA) linkers with copper ions (Cu-BTA-H), as a cathode for ZIBs. The large ratio of active sites and dual redox mechanism of Cu-BTA-H, including the one-electron-redox reaction over copper ions (via Cu2+/Cu+) and the two-electron-redox reaction over organic ligands (via C=N/C-N), effectively enhance its reversible capacity. Meanwhile, the abundant porosity, small band gap, high crystallinity, and stable coordination structure of CuBTA-H endow it with fast ion/electron transport and effectively hinder the dissolution of organic ligands during cycling, respectively. Consequently, Cu-BTA-H possesses a high reversible capacity of 330 mAh g-1 at 200 mA g-1 and excellent rate performance and long-cycle stability, with a high capacity of 106.1 mAh g-1 at 2.0 A g-1 after 500 cycles and a high Coulombic efficiency of similar to 100%. The proposed conductive MOFs with dual redox-active sites provide an efficient approach for constructing fast, stable, and high-capacity energy storage devices.
