Abstract Recently, single-atom catalysts (SACs) have been found to be one of the promising candidates for oxygen electrocatalysis in rechargeable lithium-oxygen batteries (LOBs), owing to their high oxygen electrocatalytic activity and high stability originated from their unique coordination environments and electronic properties. As a new type of catalysts for LOBs, the advancements have never been reviewed and discussed comprehensively. Herein, the breakthroughs in the design of various types of SACs as the cathode catalysts for LOBs are summarized, including Co-based, Ru-based, and other types of SACs. Moreover, considerable emphasis is placed on the correlations between the structural feature of the SAC active sites and the electrocatalytic performance of LOBs. Finally, perspective and challenges of SACs for practical LOBs are also provided. This review could provide an intensive understanding of SACs for designing efficient oxygen electrocatalysis and offers a useful guideline for the development of SACs in the field of LOBs.

AbstractInferior charge transport in insulating and bulk discharge products is one of the main factors resulting in poor cycling stability of lithium–oxygen batteries with high overpotential and large capacity decay. Here we report a two-step oxygen reduction approach by pre-depositing a potassium carbonate layer on the cathode surface in a potassium–oxygen battery to direct the growth of defective film-like discharge products in the successive cycling of lithium–oxygen batteries. The formation of defective film with improved charge transport and large contact area with a catalyst plays a critical role in the facile decomposition of discharge products and the sustained stability of the battery. Multistaged discharge constructing lithium peroxide-based heterostructure with band discontinuities and a relatively low lithium diffusion barrier may be responsible for the growth of defective film-like discharge products. This strategy offers a promising route for future development of cathode catalysts that can be used to extend the cycling life of lithium–oxygen batteries.
