High-Capacity Lithium–Air Cathodes

Lithium-oxygen (air) has one of the largest theoretical energy densities of any practical electrochemical couple. This paper will discuss the architecture of an advanced Li-air cathode with an average voltage of 2.33 V and a gravimetric capacity of 5813 mAh/g of carbon. This is the first time such a high capacity has been achieved at a current density of 0.1 mA/cm 2 and without the use of catalysts.
