SiO2/C composite as an anode material of lithium ion batteries was prepared by a facile synthesis method using raw materials of polyaniline and silicon dioxide. The SiO2/C composite shows the higher reversible capacity of 533.4 mAh g−1 after 100th cycles with good cycling stability. This improvement of electrochemical performance of the synthesized composite is benefit from the carbon coated on the SiO2 nanospheres, which improves the electrical conductivity and restrains the volume variation during the lithiation and delithiation process. Due to the superior electrochemical performance, the SiO2/C composite prepared via facile synthesis could be promising as anode materials with high capacity, low-cost for lithium-ion batteries.
