The present invention relates to a porous core-shell structure anode active material for electrochemical devices and a method of manufacturing the same. More particularly, the present invention relates to a core shell structure comprising a porous metal powder and a polymer layer formed on the surface of the metal powder, A negative electrode active material for chemical devices, and a method of manufacturing the same. The negative electrode active material for a electrochemical device having a porous core-shell structure according to the present invention includes a polymer surface layer formed on the surface of a porous metal powder capable of intercalating and deintercalating lithium ions, thereby allowing movement of lithium ions, Can withstand the stress of change, is high capacity, and can increase the battery capacity per volume. |
