Lithium-air batteries have the potential to store more energy than other battery types. They have the potential to store 5–15 times the specific energy of current lithium-ion batteries.
For comparison, tThe the energy density of gasoline is approximately 13 kW·h/kg while the theoretical energy density of the lithium-air battery is 12 kW·h/kg.
Another advantage is that lithium-air batteries have a solid-state design that is attractive from a safety standpoint. It eliminates the possibility of rupture and ignition.
