In this work, one-dimensional (1D) NiCo2S4 nanotubes with sulfur vacancies (Vc-NiCo2S4) were designed effectively via the electrostatic spinning and chemical bath deposition (CBD) process. As-spun polyacrylonitrile (PAN) nanofibers containing surfactant were taken as hard templates. Through the in-situ growth and etching process, NiCo2S4 nanotubes covered with a large number of nanosheets were generated. Sulfur vacancies were introduced by the following chemical reduction. The influence of defects was systematically discussed through structure analyses and electrochemical properties. As-obtained Vc-NiCo2S4 not only maintains the original hierarchical nanotube characteristic, but also boost the electrochemical behaviors. Due to the defect treatment, Vc-NiCo2S4 nanotubes have a higher specific capacity (1046 F g(-1) at a current density of 1 A g(-1)) and enhanced rate capability. A symmetrical supercapacitor (SSCs) device assembled by Vc-NiCo2S4 nanotubes displays a high energy density of 31.8 Wh kg(-1) at the power density of 260 W kg(-1). These results indicate that the construction of 1D hierarchical nanotubes and sulfur vacancies could provide effective strategy to promote the performance of supercapacitors. [GRAPHICS] .
