Positive electrode material for lithium secondary battery and lithium secondary battery including same

A positive electrode material for a lithium secondary battery, consisting of:

• a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material comprising a transition metal (M) to enable reversible intercalation and deintercalation of lithium, and
• a coating layer comprising molybdenum oxide is formed on the positive electrode active material,
• wherein the positive electrode active material comprises Li1.25+y[Mn0.45Ti0.35]0.975M0.025O2 and the coating layer comprises LixMoOz, wherein x, y, and z are satisfying numerical ranges of 0≤x≤6, −0.02≤y≤0.02, and 2≤z≤4,
• wherein the transition metal (M) is selected from the group consisting of W, Cr, Al, Ni, Co, V, and Zn.
