| 摘要 |
The present invention relates to an anode active material having a double-coating layer of a first coating layer and a second coating layer, a preparation method thereof, an anode including the same, and a lithium secondary electrode including the anode, wherein the anode active material has an excellent power property, effective inhibition of a sub-reaction with an electrolyte, in particular, an electrolyte containing PC, and excellent electrical conductivity. According to the anode active material of the present invention, a sub-reaction with an electrolyte, in particular, an electrolyte containing PC can be effectively prevented and electrical conductivity can be improved, thereby providing a lithium secondary battery including the anode active material, wherein a drop in an open-circuit voltage (OCV) thereof can be mitigated and rate capability and high rate properties can be improved. |
