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. 본 발명은 리튬 이차전지용 음극으로서, 음극 집전체; 상기 음극 집전체 상에 형성되고, 제1 음극 활물질로서, 천연 흑연을 포함하는 제1 음극 합제층; 및 상기 제1 음극 합제층 상에 형성되고, 제2 음극 활물질로서, 저팽창 천연 흑연을 포함하는 제2 음극 합제층을 포함하는 음극 및 이를 포함하는 리튬 이차전지에 관한 것이다.
