摘要：
Nanostructured Si-C composite materials were prepared by dispersing nanocrystalline Si in carbon aerogel and subsequent carbonization. Through this process, nanosize Si was homogeneously distributed in a carbon matrix. The Si-C composites exhibit a reversible lithium storage capacity of 1450 mAh/g when used as anodes in lithium-ion cells. The nanostructured Si-C composite electrodes demonstrated good cyclability. The Si-C composites could provide a novel anode material for lithium-ion batteries. (C) 2004 Published by Elsevier B.V.
