Abstract

The present invention relates to a method for manufacturing a cathode active material and a cathode active material obtained by the manufacturing method the method including the steps of: (S1) forming a cell unit which is a coating layer including a carbon material on a surface of a core unit including silicon oxide particles thereby manufacturing a core cell structured silicon oxide carbon composite; (S2) forming a silicon oxide lithium alloy by mixing and heat processing the silicon oxide carbon composite with lithium salt including oxygen thereby manufacturing a core cell structured (SiO Li) C (0 < x < 1.5 0 < y < 4) composite; and (S3) cleaning and drying the surface of the manufactured core cell structured (SiO Li) C composite. According to the method for manufacturing a cathode active material which is a core cell structured (SiO Li) C composite of the present invention since a coating layer of a carbon material is included on the surface of a silicon oxide core oxygen of lithium salt including the oxygen is prevented from being infiltrated into silicon oxide so that it is easy to control the proportion of oxygen in the silicon oxide. Also the cathode active material of the present invention is subjected to a process of removing a residual lithium source and a byproduct generated by a reaction between a lithium source and silicon oxide thereby preventing the slurry of the cathode active material from gelling. In addition the cathode active material of the core cell structured (SiO Li) C composite according to the manufacturing method of the present invention has a high capacity excellent lifetime characteristic and capability to control the thickness of swelling.
