METHOD FOR CONTINUOUSLY PREPARING SILICON NANOPARTICLES, AND ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY COMPRISING SAME

摘要

This invention relates to a method of manufacturing silicon nanoparticles, wherein the deterioration of an electrode due to the volume change of silicon can be minimized and electrical contact can be improved, thus ensuring high capacity and cycle characteristics of a battery, and to an anode active material using silicon nanoparticles manufactured thereby. The method of continuously manufacturing silicon nanoparticles includes feeding a silane gas and a carrier gas into a reactor, decomposing the silane gas in the reactor, and recovering the silicon nanoparticles.
