Metal–air electrochemical cell
The Li–air battery discharge reaction between Li and oxygen Li2O, according to 4Li + O2 → 2Li2O, has an open-circuit voltage of 2.91 V and a theoretical specific energy of 5210 Wh/kg. Since oxygen is not stored in the battery, the theoretical specific energy excluding oxygen is 11140 Wh/kg (40.1 MJ/kg). Compare this to the figure of 12,200 Wh/kg (44 MJ/kg) for gasoline (see petrol energy content).
