Beschreibung
Zusammenfassung:	Disclosed is a positive active material for a rechargeable lithium battery that includes a first compound represented by Chemical Formula 1 and a second compound having a smaller particle diameter than the first compound and represented by Chemical Formula 2, wherein the first compound and the second compound have a Ni content of about 50 at% to about 60 at% of the metal elements excluding Li, and a rechargeable lithium battery including the first compound and the second compound satisfies Relation 1 in a differential capacity (dQ/dV)-voltage charge/discharge graph.
