Abstract
The present invention provides a lithium-air secondary battery that is capable of effectively preventing deterioration of an alkaline electrolytic solution, air electrode, and negative electrode and has a long life and high long-term reliability. The lithium-air secondary battery comprises an air electrodefunctioning as a positive electrode, an anion exchangerprovided in close contact with one side of the air electrode and composed of a hydroxide-ion conductive inorganic solid electrolyte, a separatorprovided away from the anion exchanger and composed of a lithium-ion conductive inorganic solid electrolyte, a negative electrodeprovided so as to be capable of supplying and receiving lithium ions to and from the separator and comprising lithium, and an alkaline electrolytic solutionfilled between the anion exchanger and the separator.
