description The present invention relates to a negative electrode including multiple composite conductive agents that can improve electrical conductivity and electron mobility while improving energy density, and a lithium secondary battery including the same. The negative electrode for a lithium secondary battery according to the present invention includes: a negative electrode active material including a carbon-based material and a metal-based compound; a binder; and a multiple composite conductive agent including a carbon-based conductive agent and a metal-based conductive agent having different physical properties and shapes from each other. 본 발명은 에너지밀도를 향상시키면서 전기전도도와 전자이동성을 향상시킬 수 있는 다중 복합 도전제를 함유하는 음극 및 그를 포함하는 리튬이차전지에 관한 것이다. 본 발명에 따른 리튬이차전지용 음극은 탄소계 소재와 금속계 화합물을 함유하는 음극 활물질, 바인더, 및 물성과 형상이 서로 다른 탄소계 도전제와 금속계 도전제를 함유하는 다중 복합 도전제를 포함한다.
