POSITIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME

摘要

The present invention relates to a conductive agent/positive active material composite for a lithium secondary battery. The composite includes a positive active material capable of reversibly intercalating/deintercalating lithium ions, and a conductive agent on the surface of the positive active material. The conductive agent comprises a first conductive agent having a specific surface area ranging from about 200 to about 1500 m 2 /g and a second conductive agent having a specific surface area of about 100 m 2 /g or less.
