Lithium-air battery and lithium anode composite thereof

A lithium-air battery having a lithium anode composite and an air electrode. The lithium anode composite includes a plate-shaped or strip-shaped anode current collector; two plate-shaped anode layers made from metallic lithium, an alloy primarily composed of lithium, or a compound primarily composed of lithium and arranged to sandwich a part of the anode current collector; two plate-shaped isolating layers made from glass ceramics having lithium ion conductivity and arranged to sandwich another part of the anode current collector and the whole of the two anode layers; and a junction provided to join and close outer peripheral portions of the two isolating layers with rest of the anode current collector being exposed outward between the two isolating layers. The air electrode includes an air electrode layer having an electroconductive material and a plate-shaped or strip-shaped air electrode current collector electrically connected to the air electrode layer.
