Abstract
The present invention provides a positive electrode active material for a lithium secondary battery which is capable of preventing the degeneration of a positive electrode active material and the generation of a gas during operating a battery due to humidity, by including a surface treatment layer of an amorphous glass including an alkali metal oxide and an alkaline earth metal oxide on the surface of a core including a lithium composite metal oxide and by decreasing humidity reactivity, and a secondary battery including the same.
