Abstract

A negative electrode plate for a rechargeable lithium battery includes a negative electrode active material. The negative electrode active material includes 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 each formed from primary particles, with an amorphous carbon coating layer surrounding secondary particles, and with the first negative electrode active material has an orientation degree of 90 or less and a d002 of 3.356 Å to 3.360 Å, The second negative electrode active material is graphite. The binder includes a (meth)acrylic based binder.
