- - Cathode for lithium-air battery using passivation layer with metal catalyst manufacturing method thereof and lithium-air battery comprising the same

摘要

The present invention relates to a positive electrode of a lithium-air battery having a side-reaction preventing film to which a metal catalyst is partially introduced, and a method for producing the same, and more particularly, An anode and a method of manufacturing the same. The lithium-air battery according to the present invention suppresses side reactions at the interface between the positive electrode active material and the electrolyte, thereby effectively reducing the overvoltage during charging, and thus does not cause decomposition of the electrolyte, thereby improving cycle life.
