Abstract

A negative electrode may include a first negative electrode active layer and a second negative electrode active layer on a negative electrode current collector. An orientation index (O.I.) of each of the negative electrode active layers may satisfy a predetermined range, and thus adhesion of the negative electrode active layers to the negative electrode current collector is highly implemented, thereby having excellent lifespan characteristics. In addition, a secondary battery including the same has excellent output characteristics and can be charged in a short time even at a 1C-rate.
