摘要：
In order to develop active material with promising properties for supercapacitor, the feather duster-like CNT@WO3 composite is synthesized by a facial on-step solvothermal method. The as-prepared material shows the superior electrochemical properties with high specific capacitance (496 F g(-1) at 0.5 A g(-1)) and long-lasting cycle stability (96.3% retention after 8000 cycles at 100 mV s(-1)) in 0.5 mol L-1 H2SO4 electrolyte. This simple preparation method and superior performance can make significant contribution in the synthesis and future application in energy storage material. (C) 2019 Elsevier B.V.
