Abstract

The present invention relates to an electrode active material for a lithium secondary battery and to a method for manufacturing same. The electrode active material for a lithium secondary battery according to the present invention comprises: a core unit comprising (a) a first particulate made of metal (metalloids) capable of being alloyed with lithium and (b) a second particulate made of an oxide that contains both metal (metalloids) the same as the above mentioned metal (metalloids) and lithium; and a conductive carbon layer coated on an outer surface of the core unit. The electrode active material of the present invention has high capacity and improved electrical conductivity thereby achieving superior charging/discharging rate limiting characteristics.
