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

Abstract

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.
