Abstract
A negative electrode for a lithium secondary battery includes a carbon-based negative electrode active material and a silicon-based negative electrode active material together as a negative electrode active material. The negative electrode exhibits excellent characteristics of charge and discharge capacity and energy density. Furthermore, the negative electrode has the advantage of exhibiting high charge characteristics and life characteristics during long-term charge and discharge by realizing the alignment (O.I) of the carbon-based negative electrode active material after activation in a predetermined range that is lower than the alignment (O.I) of the carbon-based negative electrode active material before activation. A lithium secondary battery including the negative electrode is also provided. Further, methods of manufacturing the negative electrode and the lithium secondary battery are also provided.
