OverviewHistoryDesign and operationChallengesApplicationsSee alsoExternal links

The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy. Indeed, the theoretical specific energy of a non-aqueous Li–air battery, in the charged state with Li2O2 product and excluding the oxygen mass, is ~40.1 MJ/kg = 11.14 kW

Mesoporous SiO2 anode armour for lithium oxygen battery

Lithium metal (Li) has a very high theoretical specific energy (3,860 mAh g −1) and a low oxygen reduction potential (-3.04 V vs. standard hydrogen electrode), which makes it an ideal material for battery anode, but due to its own characteristics, Li is prone to have dendrite growth and change in volume during battery operation.

LiTFSI Concentration Optimization in TEGDME Solvent for Lithium–Oxygen

The cyclic voltammetry behaviors were valuable for practical lithium–oxygen battery systems because the charge–discharge current densities for the present lithium–oxygen batteries were smaller than those of traditional lithium ion battery systems.
