摘要：
A method of preparing a positive electrode active material for a secondary battery includes preparing a precursor of a composite transition metal oxide compound represented by Formula 1, and mixing the precursor, a lithium source, and a doping element source and sintering the mixture to form a doped lithium composite transition metal oxide, wherein the doping element source is a hydroxide-based compound.
Ni1−(x1+y1)Cox1May1(OH)2 [Formula 1]
wherein, Ma is at least one element selected from the group consisting of manganese (Mn) and aluminum (Al), and 0
