Abstract
Three dimensional pillared graphene nanostructures were grown on metal substrates through a one-step chemical vapor deposition (CVD) by introducing a mixture precursor gases (H2, C2H4). We further explored sputtering evaporation system to uniformly deposited a layer of amorphous silicon on the as grown 3D carbon nanostructure. The surface morphologies of the carbon-silicon nanocomposites were investigated by scanning electron microscopy (SEM). Cyclic voltammetry and charge-discharge are conducted to determine the performance of the 3D hybrid carbon-silicon nanostructure for lithium ion battery anode.
