Abstract: PURPOSE: A porous anode active material is provided to suppress stress and to ensure a high capacity compared with a conventional carbon-based anode active material by introducing some silica to a high-capacity active material. CONSTITUTION: A porous anode active material comprises 85-99 parts by weight of Group 14 oxides(10) and 1-15 parts by weight of silica(11) in a deactivation phase which does not react with lithium. A method for preparing the porous anode active material comprises the steps of: impregnating a Group 14 element salt-containing aqueous solution, including Group 14 elements salt and solvent in mesoporous silica(OMS); forming Group OMS-14 element oxide complex by heating the resultant; and etching the resultant with acid or a base solution.
