Carbon−Silicon Core−Shell Nanowires as High Capacity ...

We introduce a novel design of carbon−silicon core−shell nanowires for high power and long life lithium battery electrodes. Amorphous silicon was coated onto carbon nanofibers to form a core−shell structure and the resulted core−shell nanowires showed great performance as anode material. Since carbon has a much smaller capacity compared to silicon, the carbon core experiences less ...
