EDS data of 3D graphene nanostructure

3D graphene compounds with 3D nanostructure, which are synthesized by chemical decomposition of graphite and
simultaneous bonding with Si, are a very simple process compared to the complex process of synthesizing with the existing
CVD, Hummer’s method, and can mass-produce high-quality electrode materials with vertically aligned structures.
EDS1 shows that the surface is covered with 54.4% Si before the 3D nanostructure graphene is grown, and EDS2 shows
that less than 1% Si is checked after the 3D nanostructure graphene is grown. It is a surface that can prevent dendrites
because there is no Si on the surface.
