Multi-layer negative electrode comprising natural graphite and artificial graphite and lithium secondary battery comprising the same

A multilayer negative electrode comprising:

• a negative electrode current collector configured to transfer electrons between an outer lead and a negative electrode active material;
• a first negative electrode mixture layer formed on one surface or both surfaces of the current collector and comprising natural graphite and artificial graphite as a negative electrode active material;
• and
• a second negative electrode mixture layer formed on the first negative electrode mixture layer and comprising natural graphite and artificial graphite as a negative electrode active material,
• wherein an amount of the natural graphite present in the first negative electrode mixture layer is from 15% by weight to 75% by weight based on a total weight of the first negative electrode mixture layer,
• wherein an amount of the natural graphite present in the second negative electrode mixture layer is from 0.1% by weight to 10% by weight based on a total weight of the second negative electrode mixture layer,
• wherein a weight ratio of the first negative electrode mixture layer to the second negative electrode mixture layer is 1:9 to 5:5,
• wherein an amount of the artificial graphite is greater than an amount of the natural graphite based on a total amount of the first negative electrode mixture layer and second negative electrode mixture layer.
