摘要：
A positive active material for a rechargeable lithium battery includes a porous material including primary particles, and secondary particles including aggregates of a plurality of the primary particles. The porous material has a tap density of 0.3 to less than 1.0 g/cc. A positive electrode includes the positive active material. A rechargeable lithium battery includes the positive electrode including the positive active material.
