Abstract
A negative electrode plate for a rechargeable lithium battery may include a negative electrode active material, which may include a first, second, and a third negative electrode active material. The first negative electrode active material may include natural graphite and a coating layer. The natural graphite may include secondary particles. The secondary particles may include an assembly of primary particles. The coating layer may include amorphous carbon and surrounds the secondary particles of the natural graphite. The first negative electrode active material may have an orientation of 90 or less and may have a d002 ranging from about 3.356 Å to about 3.360 Å. The second negative electrode active material may include graphite. The third negative electrode active material may have a sphericity from about 0.9 to about 1.0 and may include silicon nanoparticles and an amorphous carbon coating layer disposed on a surface of the silicon nanoparticles.
