Zusammenfassung: | The present invention relates to a negative electrode for a lithium secondary battery. The present invention relates to the negative electrode and a lithium secondary battery including the same. The negative electrode comprises: a negative electrode current collector; a first negative electrode mixture layer formed on the negative electrode current collector and including natural graphite as a first negative electrode active material; and a second negative electrode mixture layer formed on the first negative electrode mixture layer and including low-expansion natural graphite as a second negative electrode active material.
