Abstract

See full text

A negative electrode for a lithium secondary battery and a lithium secondary battery including the negative electrode are disclosed. The negative electrode includes a negative electrode current collector, a first negative electrode active material layer present on the negative electrode current collector, and a second negative electrode active material layer present on the first negative electrode active material layer. The first negative electrode active material layer includes two or more kinds of first negative electrode active materials, and the second negative electrode active material layer includes a second negative electrode active material having swelling that is smaller than that of the first negative electrode active material layer. Therefore, the surface of the negative electrode does not exhibit deformation during pre-lithiation.
