The present invention relates to a method for preparing a negative-electrode active material for rechargeable lithium battery, wherein the negative-electrode active material comprises a core comprising material capable of doping and dedoping lithium; and, a carbon layer formed on the surface of the core, wherein the carbon layer has a three dimensional porous structure comprising nanopores regularly ordered on the carbon layer with a pore wall of specific thickness placed therebetween. In some embodiments, the method comprises modifying a material capable of doping and dedoping lithium with an organic functional group, mixing the modified material with an inorganic oxide, heating the mixture, and removing the inorganic oxide to form the negative-electrode active material.
