| 摘要 |
The present invention relates to an anode active material for a lithium secondary battery and a method for manufacturing same, and more specifically, to an anode active material for a lithium secondary battery having significantly improved thermal stability and battery characteristics due to a silicon compound by providing an anode material in which silicon oxide is coated on the surface of a Ni-rich anode active material, and to a method for manufacturing same. According to the present invention, a side reaction of an electrolyte solution is suppressed by uniformly coating the surface of the Ni-rich anode active material with the silicon oxide, thereby allowing manufacturing of the lithium secondary battery having superior output characteristics, high-temperature life characteristics, and thermal stability. |
