ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY WITH HIGH CAPACITY, A MANUFACTURING METHOD OF THE SAME AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME

摘要

An anode active material according to the present invention is an amorphous SiO-C complex of a core-shell structure, comprising a core part including silicon oxide (SiOx) particles of a pre-Si crystal and a shell part that is a coating layer including a carbon material and formed on the surface of at least part of the core part. Thus, the present invention provides an electrode active material and a lithium secondary battery, which have high capacity and have excellent life characteristics by efficiently inhibiting volume expansion that is a problem when using Si.
