| 英文摘要 | A co9s8/gns (graphene nanosheets) nanocomposites has been synthesized via a facile solvothermal approach followed by thermal treatment in nitrogen at 500 degrees c using graphite oxide sheets, cocl2 center dot 6h(2)o and thiourea as the starting materials. highly uniform co9s8 nanoparticles with a size of about 80-90 nm are evenly grafted on the surface of gns, forming a unique co9s8/gns hybrid nanostructure. when evaluated as anode materials for lithium ion batteries, impressive electrochemical performances of the as-prepared nanocomposites are achieved compared to that of pure bulk co9s8, with an high reversible capacity of 1480 mah g(-1). moreover, the as-synthesized nanocomposites present excellent cycling durability and high-rate capability. the improvement in the electrochemical properties could be attributed to the well-designed structure of the co9s8/gns nanocomposite which possesses large number of accessible active sites for lithium-ion insertion, fast ion diffusion rate and good electronic conductivity.
