A sandwich-type graphene composite structure formed of carbon-coated silicon nanoparticles and graphene, and a method for manufacturing the same are provided. The sandwich-type graphene composite structure is formed of a carbon-coated silicon graphene through an environmentally friendly filtration process. The formed sandwich-type graphene composite structure relieves the volume expansion of the silicon. In addition, the carbon coated on the silicon surface improves electrical conductivity and may be used as a high-capacity anode material.
