Silicon, an anode material for lithium ion batteries, has the highest theoretical specific capacity ([Formula: see text] mAh/g). The actual lithium storage capacity of [Formula: see text] mAh/g is about 10 times that of the graphite anode materials class. This study involves magnesium heat reduction of the SiO2 preparation of silicon carbon composites. The Si/SiC composite shows a high initial specific capacity of 1406.7 mAh/g with a current density of 0.1 A/g. The morphology and pore size inherited from the SiO2 aerogel counteracts the volume expansion during the lithiation/delithiation process. This paper provides an articulate methodology for designing silicon anode material for high-performance rechargeable lithium-ion batteries.

In this paper, we report a facile strategy to design and prepare reduced graphene oxide (rGO) supported MoS2 nanoplatelet (MoS2/rGO) via a solvothermal co-assembly process. It is found that in the as-obtained MoS2/rGO nanocomposite, MoS2 possesses unique platelet structure and rGO is exfoliated due to the in situ growth of MoS2 nanoplatelet, leading to a large specific surface area, facilitating rapid diffusion of lithium ions. The nanocomposite is used as a promising anode material for lithium-ion batteries and displays a high initial charge capacity (1382[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text]), excellent rate capability and cycling stability. The remarkable lithium storage performance of MoS2/rGO nanocomposite is mainly ascribed to the inherent nanostructure of the MoS2, and the synergistic effect between rGO nanosheets and MoS2 nanoplatelets.
