摘要：

SnS2 nanoparticle-loaded graphene nanocomposites were synthesized via one-step hydrothermal reaction. Their electrochemical performance was evaluated as the anode for rechargeable lithium-ion batteries after thermal treatment in an Ar environment. The electrochemical testing results show a high reversible capacity of more than 800 mA h g(-1) at 0.1 C rate and 200 mA h g(-1) for up to 5 C rate. The cells also exhibit excellent capacity retention for up to 90 cycles even at a high rate of 2 C. This electrochemical behavior can be attributed to the well-defined morphology and nanostructures of these as-synthesized nanocomposites, which is characterized by high-resolution transmission electron microscopy and electron energy-loss spectroscopy.
