Abstract

A novel Li–O2 cathode was designed with a nanocrystal iridium catalyst functionalized on the purposely deoxygenated surfaces of hierarchical graphene. Due to the synergistic effect between the ORR/OER activity and deoxygenated porous supporter, this cathode exhibited excellent battery performance, cycling 150 times with a limited capacity of 1000 mA h g−1 at a current density of 2000 mA g−1.
