- - PREAPARATION METHOD OF NITROGEN DOPED CARBON-SILICON COMPLEX AND NITROGEN DOPED CARBON SILICON COMPLEX PREPARED BY THE SAME

摘要

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