The present invention relates to an anode active material including natural graphite and mosaic coke-based artificial graphite, and a lithium secondary battery including the same. According to an embodiment of the present invention, an anode active material including natural graphite and mosaic coke-based artificial graphite is used, when applied to a lithium secondary battery, intercalation and deintercalation of lithium ions is more facilitated and conductivity of an electrode is improved even if no or little conductive material is used. Furthermore, the increase in conductivity can lead to not only a further improvement in rate performance of a lithium secondary battery but also a reduction in interfacial resistance.
An anode active material, comprising natural graphite and mosaic coke-based artificial graphite, wherein a weight ratio of the natural graphite to the mosaic coke-based artificial graphite is 1:0.1 to 1:1;
