Abstract

Lithium-oxygen (Li-O₂) battery has gained wide interests as one potential energy storage solution for renewable energy due to its ultrahigh specific energy (∼3500 Wh kg^-1). Currently, its development has suffered from technical issues including poor rate capability, low round-trip efficiency and inferior cycling stability, which stem from the sluggish kinetics of oxygen reduction reaction and oxygen evolution reaction, irreversible formation/decomposition behavior of Li₂O₂ and parasitic reaction during discharge and charge processes. Thus, developing highly efficient electrocatalysts towards oxygen electrode reactions is urgently needed. In this review, we firstly discuss the basic structure and fundamental chemistry of Li-O₂ batteries. Key performance indexes of electrocatalyst are then highlighted and the effects of these key performance indexes of electrocatalysts on the surface and interface chemistry of oxygen electrode reactions in Li-O₂ battery are extensively clarified. Accordingly, the structure-performance relationships of different kinds of electrocatalysts are comprehensively discussed for non-aqueous Li-O₂ battery. Finally, we conclude with a summary on the challenges for achieving high-efficiency electrocatalysts and an outlook on pointing out the promising approaches for developing advanced oxygen electrocatalyst for Li-O₂ battery.
