Claim 0:
1. A composite negative electrode active material, comprising:
a silicon-based core particle;
an outer carbon coating layer positioned on a surface of 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,
wherein the conductive structure comprises at least one 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.
