1. the preparation method of a lithium ion battery negative, it may further comprise the steps:

  • Provide one highly greater than 100 microns carbon nano pipe array, the part CNT twines each other in this carbon nano pipe array;

    Adopt blade that above-mentioned CNT is scraped the acquisition carbon nanometer tube material from substrate, the part CNT keeps the state of winding each other in this carbon nanometer tube material;

    Add in the solvent above-mentioned carbon nanometer tube material and wadding a quilt with cotton processing acquisition carbon nanotube flocculent structure, attract each other, twine through Van der Waals force between the CNT, form network-like structure;

    AndAbove-mentioned carbon nanotube flocculent structure is separated from solvent, and formation one carbon nano-tube film is handled in this carbon nanotube flocculent structure typing, to obtain lithium ion battery negative.
