The lithium–oxygen (Li–O2) battery with high energy density of 3860 Wh kg−1 represents one of the most promising new secondary batteries for future electric vehicles and mobile electronic devices. However, slow oxygen reduction/oxygen evolution (ORR/OER) reaction efficiency and unstable cycling perf...
