Catalysts for Oxygen Reduction and Evolution in Li-AIR Batteries

Technology Benefits
The findings of this study are in good agreement with oxidative current densities obtained from potentiostatic measurements of Li/Li2O2cells, reflecting the activity associated with electro-oxidation of LbO2 on these catalysts.
Technology Application
Lithium-air battery for energy storage
Detailed Technology Description
None
*Abstract
Problem:Rechargeable Li-air battery performance with aprotic organic electrolytes is limited by cathode kinetics and the effect of catalysts on the reaction kinetics of the oxygen reduction reaction (ORR) during discharge and the oxygen evolution reaction (OER) during charging in rechargeable Li-air batteries using organic electrolytes is poorly understood, hindering the progress of this technology.Technology:This invention revealed the strong influences of carbon, Au/C, and Pt/C catalysts on the charge and discharge voltages of rechargeable Li-O2 batteries. Li-O2 single-cell measurement showed that Au/C had the highest discharge activity while Pt/C exhibited extraordinarily high charging activity.
