▎ 摘　　要

A novel Li-O-2 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).
