Abstract
A method of manufacturing a negative electrode for a secondary battery. The method includes forming a first negative electrode active material layer including a carbon-based active material on at least one surface of a negative electrode current collector; and forming a second negative electrode active material layer including a silicon-based active material on a surface of the first negative electrode active material opposite the negative electrode current collector, wherein the silicon-based material is intercalated with lithium by pre-lithiation on the first negative electrode active material layer.
