Abstract:
Disclosed is a negative electrode for a lithium secondary battery having excellent electric conductivity and adhesion even though a high-loading negative electrode is used, and the negative electrode includes a negative electrode current collector; a first negative electrode mixture layer containing a first negative electrode active material, a first polymer binder and a first conductive material and formed on at least one surface of the negative electrode current collector; and a second negative electrode mixture layer containing a second negative electrode active material, a second polymer binder and a second conductive material and formed on an upper surface of the first negative electrode mixture layer, wherein the first negative electrode active material contains natural graphite and silicon oxide, and the second negative electrode active material contains artificial graphite.
