  ABSTRACT: The exceptional mechanical and electrical nature of grapheme makes it a viable candidate for enhancing the effectiveness of electrode material. In recent years, Graphene based SiO2 nanocomposites is a research hot topic of anode materials in lithium-ion batteries. In this paper, the amorphous SiO2 nanospheres/graphene composite was synthesized by hydrothermal method. Amorphous SiO2 is attached to the surface of graphene with a spherical structure and its average diameter is about 200 nm. The weight of SiO2 in the nanospheres composite is about 43%. Electrochemical tests showed that the amorphous SiO2 nanospheres/graphene composite exhibited the first charge and discharge capacity is respectively 329.5 mAhg-1 and 444.1 mAhg-1, and remain at 257.8 mAhg-1 and 274.6 mAhg-1 for 50th cycles at a current density of 200 mAg-1. The amorphous SiO2 nanospheres/graphene composite structure is novelty and the results are of great significance to the preparation and application of new anode materials.
