Metal–air electrochemical cell : ウィキペディア英語版 | Metal–air electrochemical cell
A metal–air electrochemical cell is an electrochemical cell that uses an anode made from pure metal and an external cathode of ambient air, typically with an aqueous electrolyte.〔(Metal Air Batteries, Half a Fuel Cell? )〕 ==Types== 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 5,210 watt-hours per kilogram (Wh/kg). Since oxygen is not stored in the battery, the theoretical specific energy excluding oxygen is 11,140 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)''.
