Abstract
Provided are a positive electrode active material for improving an output and a lithium secondary battery including the same. Particularly, graphite and conductive carbon which have shapes and sizes different from each other, may be simultaneously coated on a mixed positive electrode material of a 3-component system lithium-containing metal oxide having a layered structure and expressed as following Chemical Formula 1 and LiFePOhaving an olivine structure as an conductive material to improve high resistance occurrence and conductivity reduction phenomenon of a 3-component system lithium metal oxide due to a difference between particle sizes and surface areas of the 3-component system lithium-containing metal oxide and LiFePOolivine.LiNiCoMnO, 0≦<0.5, 0<<1, 0<<0.5  [Chemical formula 1]
