Core–shell tin-multi walled carbon nanotube composite anodes for lithium ion batteries

Carbon nanotube papers were produced from Multi wall carbon nanotubes (MWCNTs). Tin deposition was conducted via RF magnetron sputtering technique on the MWCNT papers to produce tin-MWCNT composite anodes. The effect of different sputtering power on the electrochemical performance of anodes was investigated. Galvanostatic charge/discharge technique was employed to determine the cyclic performance of the anode electrodes. Results showed that improvement on cyclic performance of tin anodes was achieved with novel composite tin-MWCNT composite anode structures.
