摘要：
Provided are a positive active material that has a decreased amount of Li-containing impurities that remain on a lithium transition metal composite oxide surface to decrease an amount of gas generation and has improved lifespan properties, a method of preparing the same, a positive electrode for a lithium secondary battery including the positive active material, and a lithium secondary battery including the same.
