Abstract

Disclosed are a positive electrode active material, a positive electrode, and a rechargeable lithium battery. The positive electrode active material includes a first positive electrode active material including a lithium iron phosphate-based compound, a second positive electrode active material including a lithium nickel based composite oxide, and an irreversible positive electrode additive. A weight ratio (a/b) of the first positive electrode active material (a) to the second positive electrode active material (b) is about 1.5 to about 8.5. The irreversible positive electrode additive is included in an amount of about 0.1 wt% to about 1.9 wt% based on 100 wt% of the positive electrode active material.
