Lithium-ion battery anode

A lithium-ion battery anode, comprising:

• a carbon nanotube three-dimensional network structure, comprising a plurality of carbon nanotubes intertwined with each other, the carbon nanotube three-dimensional network structure defining two opposite surfaces of the carbon nanotube three-dimensional network structure as a first surface and a second surface;
• a plurality of nano-silicon particles, coated with amorphous carbon, dispersed in the carbon nanotube three-dimensional network structure, and adhered to surfaces of the plurality of carbon nanotubes, wherein the amorphous carbon is obtained by calcining positively charged carbonizable polymers;
• and
• a carbon nanotube functional layer located on each of the first surface and the second surface, such that the carbon nanotube three-dimensional network structure is sandwiched between two carbon nanotube functional layers, wherein the carbon nanotube functional layer comprises at least two super-aligned carbon nanotube films stacked on top of each other, and carbon nanotubes in adjacent super-aligned carbon nanotube films are crossed with each other.
