An anode of a lithium battery includes a composite film, the composite film comprising a carbon nanotube film structure and a plurality of nanoscale tin oxide particles dispersed therein. A method for fabricating an anode of a lithium battery, the method includes the steps of: (a) providing an array of carbon nanotubes; (b) pulling out, by using a tool, at least two carbon nanotube films from the array of carbon nanotubes to form a carbon nanotube film structure; and (c) dispersing a plurality of nanoscale tin oxide particles in the carbon nanotube film structure to form a composite film, and thereby, achieving the anode of the lithium battery.
