Abstract
•Si/C nanocomposites obtained by ball milling are for Na-ion storage.•Nanostructuring of Si/C facilitates the Na-ion diffusion and improves the capacity.•Surface passivation by covalent SiC bonds enables the enhanced cyclability.
Si/C nanocomposites have been successfully prepared by grinding Si powders in the presence of graphite. When used as anodes for sodium-ion batteries, the as-prepared Si/C nanocomposites show significantly enhanced sodium-storage properties. In particular, the nanostructuring and close contact of the Si nanodomains and amorphous carbon enable the Si/C nanocomposites with high capacity and outstanding cyclability.
