Abstract
Provided is a lithium air battery in which a catalyst layer of a cathode contacting an electrolyte and using oxygen in the air as an active material is coupled to a membrane through which lithium ions pass, such that even though charge and discharge of the battery is repeated, the catalyst layer may not be detached, and a microporous polyolefin-based film is applied to the battery, such that a water-based electrolyte solvent may be prevented from being evaporated, thereby preventing performance deterioration due to repetition of the charge and discharge of the lithium air battery, and extending life span.
