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.
The lithium-air battery works by combining lithium ion with oxygen from the air to form lithium oxide at the positive electrode during discharge. A recent novel flow cell concept involving lithium is proposed by Chiang et al. (2009). They proposed to use typical intercalation electrode materials as active anodes and cathode materials.
Theoretically with unlimited oxygen, the capacity of the battery is limited by the amount of lithium metal present in the anode. The theoretical specific energy of the Li-oxygen cell, as shown with the above reactions, is 11.4 kWh/kg (excluding the weight of oxygen), the highest for a metal air battery.
For Li-air batteries in presence of alkyl carbonate electrolytes, the cyclic process involves the electrolyte repetitive decomposition during discharge and oxidation of decomposed products during the charge step.
The lithium air battery has a high theoretical energy density due to the light weight of lithium metal and the fact that cathode material (O 2) does not need to be stored in the battery. It has always been considered as an excellent potential candidate for electric propulsion application.
Theoretically, lithium–air can achieve 12 kW·h/kg (43.2 MJ/kg) excluding the oxygen mass. Accounting for the weight of the full battery pack (casing, air channels, lithium substrate), while lithium alone is very light, the energy density is considerably lower.

In non-aqueous lithium-air batteries, oxygen is reduced and forms solid Li 2 O 2 in the porous cathode. The capacity of this battery system is therefore mainly limited by the clog of the solid product and/or passivation of active surfaces at the porous cathode [18].To address such problem, a new type of lithium-air batteries was proposed by Visco et al. in 2004 [19].
