摘要：
Nanoporous silicon @ graphitized carbon (NPSi@C) composites have been reasonably designed and synthesized via one-step magnesiothermic co-reduction using rice husks as the silicon source and CO2 as the carbon source. In the self-assembly process, the nano-silicon prepared from rice husk-derived SiO2 is made into a porous structure and uniformly recombined with graphitized carbon formed by CO2 reduction at low temperature (680 degrees C). The nanoporous structure has contributed to accommodate the large volume effect of activated silicon and provides sufficient channels for the transfer of lith...
