| 摘要 |
The present invention relates to a silicon-based cathode active material which is suppressed of an initial irreversible by inserting a lithium film, a method for manufacturing the same, and a lithium secondary battery comprising the same. The lithium secondary battery of the present invention includes a silicon-based cathode active material, manufactured by mixing a polyacrylic acid high-strength adhesive agent and a conductive material with a silicon based cathode active material. On the surface of the silicon-based cathode active material, lithium metal is added, in order to eliminate the initial irreversible capacity. |
