Claim:
1. A method for making a composite carbon nanotube structure, comprising: providing a carbon nanotube structure and a polymer, wherein the carbon nanotube structure comprises a plurality of carbon nanotube films stacked with each other, each of the plurality of carbon nanotube films comprise a plurality of carbon nanotubes joined end to end by along van der Waals attractive force and aligned along a same direction, and an angle formed between the aligned directions of the adjacent drawn carbon nanotube films ranges from about 0 degrees to about 90 degrees; dissolving the polymer in an organic solvent to obtain a polymer solution, wherein a surface tension of the organic solvent is greater than or equal to about 40 millimeters per Newton; applying the carbon nanotube structure into the polymer solution to composite the carbon nanotube structure and the polymer; and graphitizing the polymer composited with the carbon nanotube structure to obtain the composite carbon nanotube structure comprising a graphite structure, wherein the graphitizing the polymer comprises:
