Lithium–oxygen (Li–O2) batteries have the potential to deliver 3–5 times higher specific energy than that of conventional Li-ion batteries, but they still suffer from critical challenges such as low energy efficiency and short cycle life. Such challenges are mainly caused by the parasitic reactions between cell components and reactive oxygen species during cycling, which need to be suppressed to achieve long cycle life. Metal–organic frameworks (MOFs) are an emerging type of highly porous materials and have been widely studied in catalysis and energy storage due to their large surface area and unsaturated metal sites. Recently, our group reported a MOF-based cathode for Li–O2 batteries with mitigated parasitic reactions and thus enhanced cycling performance (Energy Storage Mater. 2019, 17, 167-177). Herein, we present the rational design of MOFs for Li–O2 batteries and mechanistic studies on the enhanced battery performance using in-situ and ex-situ characterization tools.
