摘要：
Disclosed are a precursor for a rechargeable lithium battery, a positive active material including the same, a preparation method thereof, and a rechargeable lithium battery including the positive active material. More particularly, the present invention relates to a precursor including a sheet-shaped plate having a thickness of about 1 nm to about 30 nm and that is represented by the following Chemical Formula 1. NixCoyMn1-x-y-zMz(OH)2 [Chemical Formula 1] In the above Chemical Formula 1, 0
