▎ 摘　　要

A waste corn cob core-derived SiO2 @ graphene-like carbon nanocomposite (CCC) has been synthesized by a hydro-thermal and high-temperature carbonization process. The CCC material is carbonized at 900 degrees C (CCC-900). The SiO2 nanoparticle with a granule size of 100-200 nm could be grown on the graphene-like carbon nanosheets. The BET-specific surface area can be calculated to be 481.81 m(2) g(-1). When it is used as an anode material for lithium-ion battery, the CCC composite can display the foremost discharge capacity of 2051.5 mAh g(-1) at 200 mA g(-1) and the maintain capacity of 125 mAh g(-1) after 200 cycles. The high foremost discharge capacity could be attributed to the synergistic effect of SiO2 nanoparticles and graphene-like sheets.
