COMPOSITE ANODE ACTIVE MATERIAL, PREPARATION METHOD THEREFOR, AND ANODE COMPRISING SAME

Provided is a composite negative electrode active material, which includes: a silicon-based core particle; an outer carbon coating layer positioned on the silicon-based core particle; first single-walled carbon nanotubes in contact with the outer carbon coating layer, wherein the first single-walled carbon nanotubes protrude from the outer carbon coating layer; a conductive structure spaced apart from the outer carbon coating layer and including second single-walled carbon nanotubes; and a crosslinking material bonded to the first single-walled carbon nanotube and at least one of the second single-walled carbon nanotubes, wherein the at least one of the second single-walled carbon nanotubes is crosslinked with the first single-walled carbon nanotube by the crosslinking material, and wherein the conductive structure and the first single-walled carbon nanotube are connected to each other.
