Li-Air Battery Fundamentals

Ever since the possibility of fabricating a practical nonaqueous Li-air battery as reported by Abraham et al. a new renewed interest has been triggered by world battery community to bring back lithium s true advantage in the form of Li-air secondary battery system.  

It should be understood that the OER process does not involve L1O2, instead the U2O2 is directly discomposed into Li+. 

The formation of Li20 is not favored kinetically, as it requires the full cleavage of 0-0 bond. The rechargability of Li-air cell has been accomplished by electrochemical (oxidation) decomposition of Li202 with or without catalyst in the porous carbon matrix, the so-called gas diffusion electrode (GDE) at the air cathode side.
