Abstract
Provided are an anode including spherical natural graphite having a surface coated with an amorphous carbon layer, wherein a crystal orientation ratio is in a range of 0.06 to 0.08 at a compressed density of 1.40 g/cc to 1.85 g/cc, and a lithium secondary battery including the anode. Initial efficiency, electrode adhesion, and capacity characteristics of the lithium secondary battery may be improved by using the anode of the present invention in the lithium secondary battery.
