A Si/C nanocomposite anode by ball milling for highly reversible sodium storage
چکیده انگلیسی


• 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.
