The present invention relates to a process for the production of nitrogen-doped carbon-silicon composites and the nitrogen-doped carbon-silicon composites produced thereby. According to the method for producing a nitrogen-doped carbon-silicon composite of the present invention, since the composite is formed through the eutectic mixture state, the carbon-silicon composite in which silicon is uniformly dispersed in the nitrogen-doped graphite carbon continuous phase can be produced. In addition, the nitrogen-doped carbon-silicon composite thus prepared has excellent electrical conductivity, strength, and capacity retention, and thus can be used as a negative electrode active material of a lithium secondary battery. |
