Abstract
Disclosed is a negative active material for a lithium secondary battery. The negative active material includes graphitized coke having a graphitization catalyst element and non-flat artificial graphite. The negative active material for a lithium secondary battery has good electrolyte-immersibility due to the gap between the graphite particles from graphitized coke having a graphitization catalyst element, and non-flat artificial graphite. Therefore, the present invention may provide a lithium secondary battery which has good high-rate capacity and initial efficiency.
