A composite particle comprising silicon particles and a carbon coating layer coated on the surface of the silicon particles and a carbon nanofiber structure including a lattice space formed by entangling the carbon nanofibers, Wherein the particles are located in contact with an outer surface of the carbon nanofibers in the lattice space of the carbon nanofiber structure, the diameter of the carbon nanofibers is larger than the diameter of the composite particles, and the diameter of the carbon nanofibers is 100 to 2000 nm, a method for producing the same, and a lithium secondary battery comprising the same. |
