Abstract

A negative electrode plate for a rechargeable lithium battery and a rechargeable lithium battery including the same are disclosed. A negative electrode plate for a rechargeable lithium battery includes a negative electrode active material including a mixture of a first negative electrode active material, a second negative electrode active material, and a third negative electrode active material. The first negative electrode active material includes natural graphite including secondary particles (3) in which primary particles (1) are assembled and a coating layer (7) that surrounds the secondary particles and includes amorphous carbon, and the first negative electrode active material has an orientation degree of 90 or less and a d002 of 3.356 to 3.360 Å; the second negative electrode active material includes artificial graphite; and the third negative electrode active material includes a core (4) including silicon nanoparticles (2) and amorphous carbon, and an amorphous carbon coating layer (6) that surrounds the core and includes amorphous carbon.
