1. A rechargeable lithium battery, comprising:
a positive electrode; and
a negative electrode, the negative electrode including:
a current collector; and
a negative active material layer on the current collector, the negative active material including a carbon negative active material;
wherein:
the negative electrode is larger than the positive electrode;
an electrode density of the negative electrode is about 1.0 g/cc to about 1.5 g/cc, and
a DD (Degree of Divergence) value 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.
