Enhanced Cycling Stability of Hybrid Li–Air Batteries Enabled by Ordered Pd3Fe Intermetallic Electrocatalyst

Abstract
We report an ordered Pd3Fe intermetallic catalyst that exhibits significantly enhanced activity and durability for the oxygen reduction reaction under alkaline conditions. Ordered Pd3Fe enables a hybrid Li-air battery to exhibit the best reported full-cell cycling performance (220 cycles, 880 h).
