Abstract
Provided is a positive electrode active material for a lithium secondary battery including a positive electrode active material particle and an electrolyte-containing metal oxide coating layer having a porous structure and a method of manufacturing the same. A lithium secondary battery to which the positive electrode active material including the electrolyte-containing metal oxide coating layer is applied can have improved charge/discharge efficiency and lifespan characteristics at the same time.
