摘要：

Flower-like SnS2 fabricated by a novel hydrothermal approach are assembled by nano-plates with 1-2 mu m in width and 5-10 nm in thickness. Carbon nanotubes are introduced to form a cross-winding network on the surface of SnS2 nano-plates, which improve the conductivity and Na+ diffusion of composites. The composites are explored as an anode for sodium-ion battery, and deliver an excellent rate performance. The composites get a reversible capacity of 460 mA h g(-1) at 20 mA g(-1) and 180 mA h CI. even increased to 1280 mA g(-1), which reveal the importance of carbon nanotubes network to optimize the fast charge-discharge capabilities of SnS2 flowers.
