Abstract
The present invention provides a negative electrode for a secondary battery, the negative electrode including a negative electrode current collector, a first negative electrode active material layer located on the negative electrode current collector, and a second negative electrode active material layer located on the first negative electrode active material layer, such that resistance in the electrode is decreased due to an increase in adhesion between the negative electrode current collector and the active material and cohesion between the active materials, thereby significantly improving capacity and lifespan characteristics of a battery, a method of fabricating the same, and a secondary battery including the same.
