Li−O 2 batteries with extremely high theoretical energy density have garnered great attention over the last decade. To realize practical applications, numerous efforts have been made to solve the critical problems. Li anodes, as one of the most important part of Li−O 2 batteries, play a vital role in improving the cycle life of batteries. The unresolved issues related to lithium dendrites and contaminant (O 2 and H 2 O) crossover from cathodes to anodes dramatically influence the battery performance. In this review, we analyze the challenging issues of Li anodes in Li−O 2 batteries and summarize the strategies to achieve high performance of Li−O 2 batteries and the recent progress in this field. The prospective development of highly stable Li anodes is also discussed.
