Abstract:
A negative electrode and a secondary battery including the negative electrode. The negative electrode including a current collector and a negative electrode active material layer, wherein the negative electrode active material layer includes negative electrode active material particles, the negative electrode active material particles include natural graphite particles and a carbon coating layer disposed on the natural graphite particles. The negative electrode active material particles have a D50 of 6 μm to 9.2 μm and a half-width of 5.0 μm to 5.5 μm based on a particle size distribution, and the specific surface area of the negative electrode active material particles is from 0.6 m2/g to 2.2 m2/g.
