摘要： The present disclosure relates to a lithium-ion battery anode comprising a flexible and free-standing carbon nanotube film, and a plurality of titanium dioxide nanoparticles uniformly adsorbed on a surface of each of the plurality of carbon nanotubes. The flexible and free-standing carbon nanotube film comprises a plurality of carbon nanotubes. A particle size of each of the plurality of titanium dioxide nanoparticles is less than or equal to 30 nanometers. The present disclosure also relates to a lithium-ion battery comprising the lithium-ion battery anode.

摘要： The present disclosure relates to a method for making a lithium-ion battery anode. The method comprises the steps of scratching off a carbon nanotube array to obtain a plurality of carbon nanotubes, adding the plurality of carbon nanotubes into a solvent, and ultrasonically dispersing the solvent to make the plurality of carbon nanotubes form a three-dimensional network-like structure; adding a titanium salt into the solvent, wherein the titanium salt hydrolyzes to form a plurality of titanium dioxide particles, and the plurality of titanium dioxide particles are adsorbed on surfaces of the plurality of carbon nanotubes; and separating the nanotube three-dimensional network structure from the solvent to form a precursor, and drying the precursor to form a titanium dioxide-carbon nanotube composite film.
