摘要

Double-walled carbon nanotubes could be synthesized by arc-discharge method using ball-milling mixtures of iron, cobalt, nickel and sulfide as catalysts. Structures of these carbon nanotubes were characterized by TEM, HRTEM and Raman spectroscopy. Also the lithium insertion properties were examined. The results showed that the irreversible capacity of the double-walled carbon nanotube lithium ion batteries is high, which is considered to be related to the formation of SEI on the surface of the electrodes in the process of electrochemistry reaction.
