1. A method for making a composite carbon nanotube structure, comprising:
providing a carbon nanotube structure and a polymer; compositing 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:
pre-oxidizing the polymer composited with the carbon nanotube structure at a pre-oxidizing temperature to form a pre-oxidized polymer;heating the pre-oxidized polymer from the pre-oxidizing temperature to a graphitizing temperature; andcarbonizing the pre-oxidized polymer composited with the carbon nanotube structure at the graphitizing temperature, wherein a mass ratio between the graphite structure and the composite carbon nanotube structure is controlled by a time of heating the pre-oxidized polymer from the pre-oxidizing temperature to the graphitizing temperature, wherein the mass ratio between the graphite structure and the composite carbon nanotube structure is increased by expanding the time of heating the pre-oxidized polymer from the pre-oxidizing temperature to the graphitizing temperature.
