Hierarchical three-dimensional porous SnS_2/carbon cloth anode for high-performance lithium ion batteries

摘要

Hierarchical three-dimension (3D) porous SnS2/carbon clothes were synthesized via a facile polyol re-fluxing process. The as-synthesized samples were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emmet-Teller (BET) and UV-vis diffuse reflectance spectrometer (UV-vis DRS). The 3D porous SnS_2/carbon clothes-based lithium ion batteries exhibited high reversible capacity and good rate capability as anode materials. The good electrochemical performance for lithium ion storage could be attributed to the special nanostructure, leading to high-rate transportation of electrolyte ion and electrons throughout the electrode matrix.
