The invention discloses a carbon nanotube conductive coating current collector, which comprises a metal current collector and a carbon nanotube conductive coating, wherein the carbon nanotube conductive coating coats the surface of the metal current collector; the thickness of the carbon nanotube conductive coating is 1-50 microns; and the surface of the carbon nanotube conductive coating is provided with a mesh micro crack structure and a coarse porous structure. The invention further provides a preparation technology of the carbon nanotube conductive coating current collector. The carbon nanotube conductive coating disclosed by the invention provides a good conductive network for an electrode, and is especially obvious for an electrode material with relatively poor conductivity; meanwhile, dense micro cracks are formed in the surface after the carbon nanotube conductive coating is dried through preparing conductive paste with different dispersion effects; and an electrode coating can be embedded among the micro cracks, so that the contact area of the electrode coating and the conductive coating is greatly improved; the binding force between the electrode coating and the current collector is improved; the internal resistance of a battery is reduced; the lifetime of the battery is prolonged; and the high-rate capability is improved.
