Abstract
The anode active material of the present invention comprises silicon-based particles obtained from at least one of silicon, a silicon oxide and a silicon alloy, and the silicon-based particles have a faceted shape, thereby providing high capacity and good life characteristics without causing any deterioration which has been generated in the use of conventional silicon-based particles, and eventually providing a lithium secondary battery having such characteristics.
