Abstract
The present invention provides a positive electrode material for a lithium secondary battery comprising a positive electrode active material in which a part of vanadium in vanadium oxide is substituted by molybdenum. In the positive electrode active material, 0.5 to 4.5% of vanadium based on the number of vanadium atoms is substituted with molybdenum. The present invention also provides a lithium secondary battery comprising a positive electrode including the above positive electrode material and a positive electrode current collector; a negative electrode; a separator; and an electrolyte solution.
