Manufacturing method of metal nano particle-carbon complex, metal nano particle-carbon complex made by the same, and electrochemical device including the same

The present invention is a metal nanoparticle-relates to an electrochemical device comprising the carbon composite spheres and this-method of producing a carbon composite spherical bodies, whereby the prepared metal nanoparticles by. Metal nanoparticles of the present invention, carbon composite spherical method of producing bodies are metal nano-causing polymerization at the surface of the particles, since the by carbonizing the resulting polymer by the heat treatment, the metal nanoparticles uniformly dispersed in the polymer metal nanoparticles - possible to produce a carbon composite spheres may, whereby the metal nanoparticles prepared by-the case of a lithium secondary battery comprising a carbon composite spheres exhibit improved charge and discharge characteristics and life characteristics.
