Abstract: PURPOSE: A lithium ion air battery having interlayer inserted electrode is provided to drastically increase energy density and to enhance durability and safety of charge and discharge cycles. CONSTITUTION: A lithium ion air battery having interlayer inserted electrode comprises a lithium metal electrode and an interlayer inserted electrode which is inserted between the lithium metal electrode and an air electrode. The interlayer inserted electrode is used as a negative electrode after being charged, and generates electrical energy by reacting with the air electrode which is a positive electrode. The interlayer inserted electrode is formed by double-sided coating of a mesh shaped metal with a material capable of being intercalated. The material capable of being intercalated is selected from a group consisting of carbonaceous material, graphite, silicon, tin-based, lithium tin oxide base.
