Abstract

See full text

The present invention relates to a reduced-graphene-oxide/silicon-metal-particle composite, a method of manufacturing the composite and an electrode for a secondary battery including the composite. The method of manufacturing the reduced-graphene-oxide/silicon-metal-particle composite includes preparing a reduced-graphene-oxide dispersion solution by reducing graphene oxide formed through cation-pi interaction, preparing a reduced-graphene-oxide/silicon-metal-particle dispersion solution by mixing the reduced-graphene-oxide dispersion solution with silicon metal particles, and manufacturing a composite powder having a core-shell structure by drying the reduced-graphene-oxide/silicon-metal-particle dispersion solution. Thereby, reduced graphene oxide can be formed using the graphene oxide dispersion solution having few defects and high purity obtained through cation-pi interaction, and dried to afford a composite powder having a core-shell structure, which is applicable to an electrode for a secondary battery.
