Lithium air battery''s specific energy advantage over lithium-ion batteries could arise from two potential sources: (1) one of the reactants, O 2, is not stored in the battery but comes from breathing air as in a fuel cell and (2) the use of light materials for the electrodes, i.e., Li metal, as the anode rather than intercalated graphite (LiC 6) and possibly porous C for the

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. [ 1 ] Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy.
Lithium in the anode undergoes a redox reaction, and lithium ions (Li +) are constantly transported through the electrolyte to the cathode and react with oxygen molecules. Lithium oxide (Li 2 O) and lithium peroxide (Li 2 O 2) are generated in the air cathode. The general reaction are presented as:
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.
Lithium oxides form during discharging cycle as lithium ions are transferred to the cathode and react with incoming oxygen. The recharging process involves the reduction of lithium oxides (Li 2 O and Li 2 O 2). However, Li 2 O is not electrochemically active and subsequently not participating reversible reactions.
In typical Li-air batteries, oxygen gas is used as a cathode material along with a catalyst and porous carbon as a Li 2 O 2 reservoir in a cathode. Li metal is used as an anode which plays the basic role of Li source in Li-air batteries.
