The ultrahigh theoretical energy density of lithium–sulfur (Li–S) batteries has attracted intensive research interest. However, most of the long-term cycling performance parameters are strongly dependent on the utilization of the electrolyte, which is considered as an indispensable component in Li–S batteries. Over the past few decades, numerous research studies around LiNO3 as an electrolyte additive have been carried out and have been confirmed to significantly upgrade the electrochemical performance of Li–S batteries, but the mechanism of performance improvement is still not well-understood. In this minireview, we revisit the controversial issues surrounding LiNO3 based on recent representative studies, provide a comprehensive understanding of the role of LiNO3 in the Li–S battery system, and specifically discuss what the panoramic view of the solid electrolyte interface film formed by LiNO3 on the surface of Li metal anodes looks like. Finally, we present general conclusions and unique insights into the future development of Li–S batteries. This minireview aims to provide a tutorial reference for researchers who are ready to enter or are active in the field of Li–S batteries.

解读 LiNO3 添加剂在 Li-S 电池中的作用
锂硫（Li-S）电池的超高理论能量密度引起了广泛的研究兴趣。然而，大多数长期循环性能参数很大程度上取决于电解质的利用率，而电解质被认为是锂硫电池中不可或缺的组成部分。在过去的几十年里，围绕LiNO 3作为电解质添加剂的大量研究已经被证实可以显着提升Li-S电池的电化学性能，但性能提升的机制仍不清楚。在这篇小评论中，我们根据最近的代表性研究重新审视了围绕 LiNO 3的争议问题，全面了解 LiNO 3的作用在Li-S电池系统中，具体讨论了LiNO 3在Li金属负极表面形成的固体电解质界面膜的全景图。最后，我们对锂硫电池的未来发展提出了一般性结论和独特见解。本综述旨在为准备进入或活跃于锂硫电池领域的研究人员提供教程参考。
