Abstract
A negative electrode for a lithium secondary battery, where the negative electrode includes a negative electrode current collector, a negative electrode active material layer, a lithium layer that is positioned between the negative electrode current collector and the negative electrode active material layer, and a primer layer that is positioned between the negative electrode current collector and the lithium layer, and a manufacturing method thereof. This results in a simple method and a negative electrode with high capacity characteristics.
