ABSTRACT:
A carbon anode active material for lithium secondary battery comprising a cluster or thin film layer of a metal or metal oxide coated onto the surface of the carbon active material, a preparation method thereof, and a metal-carbon hybrid electrode and a lithium secondary battery comprising the same. The carbon active material is prepared through a gas suspension spray coating method. An electrode comprising the carbon active material according to the present invention shows excellent conductivity, high rate charge/discharge characteristics, cycle life characteristics and electrode capacity close to theoretical value.
