1. A negative electrode for a rechargeable lithium battery, the negative electrode comprising:
a current collector; and
a negative active material layer on the current collector, the negative active material including a carbon negative active material;
wherein:
a DD (Degree of Divergence) value of the negative electrode, as defined by the following Equation 1, is about 24 or greater,
DD (Degree of Divergence)=(Ia/Itotal)*100 [Equation 1]
in Equation 1:
Ia is a sum of peak intensities at 2θ=42.4±0.2°, 43.4±0.2°, 44.6±0.2°, and 77.5±0.2° measured by XRD using a CuKα ray, and
Itotal is a sum of peak intensities at 2θ=26.5±0.2°, 42.4±0.2°, 43.4±0.2°, 44.6±0.2°, 54.7±0.2°, and 77.5±0.2° measured by XRD using a CuKα ray,
the negative electrode has an active region facing a positive electrode and an inactive region not facing the positive electrode, and
a DD value of the inactive region of the negative electrode is about 24 to about 70.
