To address these issues, this article offers a thorough examination of the latest innovations aimed at stabilizing the Li metal anode within Li-S batteries.

Benefiting from the designs in the electrolyte, interface, and lithium host, several attempts have been made in the commercial application of LMBs. However, the application of lithium anode introduces additional safety risks and potential catastrophic accidents due to the high activity of lithium metal and dendrite during the electrochemical cycles. A comprehensive understanding of challenges and design issues on the safety hazards of LMBs in life cycle management is imperative for safe and commercial applications of LMBs. This paper first reviews emerging key safety issues and promising corresponding enhancements of LMBs during their production, utilization, and recycling. The wet air instability of lithium metal anode and gas production during activation have undoubtedly become the most intractable problems in LMBs production. It is necessary to use spraying technology to build a good protection layer upon lithium metal anode. Then, the growth of lithium dendrites poses a higher challenge to the utilization of LMBs, which requires the design of better electrolyte, anode skeleton, and other strategies as well as the prediction of LMBs life through big data and other methods.
