In order to investigate the relationship between the electrochemical characteristics of the carbon films and deposition technique, three different vacuum techniques were employed such as RF (radio frequency)-magnetron sputtering of C-60, plasma assisted thermal evaporation of C-60 and ion beam assisted thermal evaporation of fullerene C-60. From the physical and chemical characterization tests, we found that the carbon films produced by those above techniques mainly consist of sp(2)/sp(3) hybridized amorphous carbons. Electrochemical tests implied that the cyclic performance was enhanced by the fullerene C-60 coating on lithium metal anode in comparison to the pure lithium metal one. This enhanced performance is due to the formation of thin carbon film on the surface of lithium metal anode which plays a role as a passive layer against the side reaction between lithium metal and the electrolyte.
