The effect of oxygen pressures on the electrochemical profile of lithium/oxygen battery

The influences of oxygen pressure on the performance of a lithium/oxygen battery using non-aqueous electrolyte were investigated in this paper. Oxygen pressures were adjusted from 1 to 10 atm. It was found that, at all examined discharge rates from 0.1 to 1.0 mA cm(-2), the discharge capacity increased with the increasing of oxygen pressure, especially at a high discharge rate. The morphology of the discharge product was found to relate to discharge rate and oxygen pressure by scanning electron microscopy observation.
