- Lithium–air_battery abstract "The lithium-air battery, Li-air for short, is a metal-air battery chemistry that uses the oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. Originally proposed in the 1970s as a possible power source for electric vehicles, Li-air batteries recaptured scientific interest in the late 2000s due to advances in materials technology and an increasing demand for environmentally safe and oil-independent energy sources.The major appeal of the Li-air battery is the extremely high energy density, a measure of the amount of energy a battery can store for a given mass. A lithium-air battery has an energy density (per kilo) comparable to traditional gasoline per kilo. Li-air batteries gain this advantage in energy density since they use oxygen from the air instead of storing an oxidizer internally.The technology requires significant research in a variety of fields before a viable commercial implementation is expected. Four approaches are being pursued; aprotic, aqueous, solid state, and mixed aqueous/aprotic.Lithium batteries have received considerable attention over the past 40 years. The first commercial lithium cells arrived 20 years ago. Lithium batteries offer high performance due to the intrinsic high specific energy densities.Metal-air batteries, specifically zinc, have received attention due to the potential for high energy densities. The theoretical specific energy densities for metal-air batteries are higher than for ion-based approaches, due to the use of atmospheric oxygen as the cathode, eliminating a traditional cathode structure. Recently, lithium-air batteries have been proposed as the next step in lithium battery architecture, due to the high specific energy density of lithium with respect to air (3840 mA·h/g).A major force in lithium-air battery development is the demand for advanced battery technology for the automotive sector. The energy density of gasoline is approximately 13 kW·h/kg, which corresponds to 1.7 kW·h/kg of energy provided to the wheels after losses. The theoretical energy density of the lithium-air battery is 12 kW·h/kg (43.2 MJ/kg) excluding the oxygen mass. It has been theorized that the same 1.7 kW·h/kg could reach the wheels using Li-air after losses from over-potentials, other cell components, battery pack ancillaries, given the much higher efficiency of electric motors.Lithium-air batteries have the potential of 5–15 times the energy density of current lithium-ion batteries.".
