Lithium-air battery and lithium anode composite thereof

A lithium-air battery comprising:

• a lithium anode composite;
• and
• an air electrode,
• wherein 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 so as to sandwich a part of the anode current collector;
• two plate-shaped isolating layers made from glass ceramics having lithium ion conductivity and arranged so as to sandwich another part of the anode current collector and the whole of the two anode layers;
• and
• a junction provided so as 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, and
• wherein the air electrode includes:
• an air electrode layer containing an electroconductive material and facing at least one of the two isolating layers;
• and
• a plate-shaped or strip-shaped air electrode current collector electrically connected to the air electrode layer.
