摘要： The present invention provides surface-modified silicon nanoparticles comprising a LixSiyOz top film and a carbon (C) coating layer on the surface of the nanoparticles by means of the addition of a lithium source and a carbon source during the manufacture of silicon nanoparticles or a post-treatment thereof. According to the present invention, the surface oxidation of the silicon nanoparticles, which would easily occur during a pulverization process, can be prevented. By using the silicon nanoparticles of which oxidation is prevented as a negative electrode material, problems related to decrease in capacity and electrolyte depletion resulting from an oxidized film can be mitigated. Thus, a deterioration in the properties of a lithium secondary battery can be prevented.

摘要： A method of preparing metal nanoparticles using a phase transfer reduction method in which a reduction reaction is adjusted by distribution equilibrium between an intermediate formed by a coordinate bond between a capping material and various metal precursors in the form of an organic phase and a reducing agent present in an aqueous phase, and a metal ink prepared from the metal nanoparticles. The method of preparing metal nanoparticles includes dissolving a metal precursor and a capping agent in an organic phase, dissolving a reducing agent in an aqueous phase, mixing the organic phase and the aqueous phase to form a precipitate, separating the precipitate, and drying the separated precipitate. The metal nanoparticles prepared using the method can be prepared to have various particle sizes according to the kind of precursors and a length of an alkyl chain of an amine used as the capping agent. As a self-quenching reaction in which growth of the nanoparticles in the aqueous layer is stopped takes place since the nanoparticle precipitate into the aqueous layer from the organic layer due to a difference in density of the metal nanoparticles formed during a reaction, a particle size of the metal nanoparticles can be easily controlled, and excellent processability in which the metal nanoparticles are easily separated/purified from the organic layer in which most reaction by-products are present can be ensured. Also, as the metal nanoparticles having various particle sizes are able to be prepared, a metal ink having various sintering temperatures spanning from a low temperature to a high temperature can be prepared using the metal nanoparticles.
