The Influence of Catalysts on Discharge and Charge Voltages of Rechargeable Li-Oxygen Batteries

This study revealed the strong influence of carbon, Au/C, and Pt/C catalysts on the charge and discharge voltages of rechargeable Li-O(2) batteries. Li-O(2) single-cell measurements showed that Au/C had the highest discharge activity, while Pt/C exhibited extraordinarily high charging activity. (C) 2010 The Electrochemical Society.
