摘要：

A novel anode material for lithium-ion batteries, SiO/graphene nanocomposite, was fabricated by a facile in situ chemical synthesis approach. The nanocomposite were characterized by X-ray diffraction, field emission scanning electron microscopy and high resolution transmission electron microscopy. SiO nanoparticles with sizes of about 50-300 nm were homogeneously located on graphene matrix. The prepared nanocomposite material exhibits an high initial specific capacity of 2285 mAh g(-1), excellent cyclic performance of 890 mAh g(-1) at 100th cycle and good rate capability, which was ascribed to the three-dimensional architecture of SiO/graphene nanocomposite. Our results indicate that SiO/graphene nanocomposite is a good candidate for high performance lithium-ion battery anodes.
