Electrochemical Performance of Silicon Nanoball Encapsulated with Graphene Shell for Anode Material of Li-ion Battery |
초록 |
In this study, we prepared a silicon nanoball encapsulated with graphene shell(Si-GB) for the anode material to get a lithium ion battery with high stability and capacity. For preparing Si-GB, electroless plating and CVD method were used. The Si-GB has a gap between the inner silicon core and the graphene shell, so that there is enough room for the volume change of silicon during charge and discharge. The morphology of Si-GB was observed by field emission scanning electron microscope (FESEM) and field emission transmission electron microscope (FETEM). Si-GB was investigated by Raman and X-ray Photoelectron Spectroscopy to identify graphene layer on the surface of the inner silicon core. The electrochemical performance of the Li-ion battery using Si-GB was investigated by battery cycler system and galvanostat system. |
