Catalysts for Oxygen Reduction and Evolution in Li-AIR Batteries

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. Christopher Noble crn@mit.edu
