1. A positive active material precursor for a rechargeable lithium battery,
the positive active material precursor comprising:
a transition metal composite oxide precursor configured to exhibit a peak full width at half maximum of a (200) plane (20θ=about 42° to about 44°) in an X-ray diffraction analysis in a range of about 0.3° to about 0.5°.
