摘要：Rational design of the electrode materials in distinctive architecture and tailored composition is critical for regulating their electrochemical properties. Herein, the novel porous zinc-cobalt sulfides (ZCS) bead-curtain-like arrays (BCA) supported by three-dimensional Ni foam (NF) (denoted as ZCS/NF BCA) are fabricated as advanced electrode for supercapacitors (SCs), which exhibit remarkable electrochemical performances in respect of superb capacity of similar to 837 C g(-1) (specific capacitance of similar to 1860 F g(-1)) at 1 A g(-1) and ultra-long cycling stability (similar to 92.9% retention after 5000 cycles at 6 A g(-1)). Furthermore, the assembled hybrid supercapacitors based on ZCS/NF BCA delivers ultrahigh energy density of similar to 88 Wh kg(-1) with a maximum power density of similar to 800 W kg(-1). The excellent properties may be ascribed to the combined contributions from the hierarchical bead-curtain architecture of ZCS/NF BCA composite and the bimetallic sulfide with abundant valence states for rich redox reactions.
