Carbon materials such as graphite have been widely used as the anode materials of secondary batteries. In spite of good stability, they are limited by low capacity. Silicon has a 4 times higher capacity than any other carbon material. It cannot be used, because it has a low stability caused by the volume expansion. In this study, we fabricated a silicon nanoball encapsulated with graphene(Si-GB) to overcome the mentioned problems. In order to form a core/shell structured graphene encapsulated silicon nanoball, The Si-GBs were made by electroless plating method CVD process. The Si-GBs were formed with a spherical void between the silicon particle and the graphene layer, by which it has a better safety against to volumetric change of anode during lithiation/ delitiation of repeated charging-discharging in secondary betteries. Morphology of the Si-GB was observed by the FESEM and the FETEM to find core-shell structured nanoball. The Si-GB was investigated by the Raman, the X-ray Photoelectron Spectroscopy to identify graphene layer on the surface of the inner silicon core.
