Lithium metal (Li0) rechargeable batteries (LMBs), such as systems with a Li0 anode and intercalation and/or conversion type cathode, lithium‐sulfur (Li‐S), and lithium‐oxygen (O2)/air (Li‐O2/air) batteries, are becoming increasingly important for electrifying the modern transportation system, with the aim of sustainable mobility. Although some rechargeable LMBs (e.g. Li0/LiFePO4 batteries from Bolloré Bluecar, Li‐S batteries from OXIS Energy and Sion Power) are already commercially viable in niche applications, their large‐scale deployment is hampered by a number of formidable challenges, including growth of lithium dendrites, electrolyte instability towards high voltage intercalation‐type cathodes, the poor electronic and ionic conductivities of sulfur (S8) and O2, as well as their corresponding reduction products (e.g. Li2S and Li2O), dissolution, and shuttling of polysulfide (PS) intermediates. This leads to a short lifecycle, low coulombic/energy efficiency, poor safety, and a high self‐discharge rate. The use of electrolyte additives is considered one of the most economical and effective approaches for circumventing these problems. This Review gives an overview of the various functional additives that are being applied and aims to stimulate new avenues for the practical realization of these appealing devices.

锂金属阳极和可充电锂金属电池的电解质添加剂：进展和展望
锂金属（Li 0）充电电池（LMB），例如具有Li 0阳极和插层和/或转换型阴极，锂硫（Li‐S）和锂氧（O 2）/空气（Li）的系统ØO 2 /空气电池，对于实现可持续交通发展的现代交通系统电气化，正变得越来越重要。尽管有些可充电LMB（例如Li 0 / LiFePO 4BolloréBluecar电池，OXIS Energy和Sion Power的Li‐S电池已在小众应用中实现了商业应用，它们的大规模部署受到许多严峻挑战的阻碍，包括锂枝晶的生长，电解质对高电压嵌入的不稳定性型阴极，硫（S 8）和O 2以及较弱的电子和离子电导率，以及它们相应的还原产物（例如Li 2 S和Li 2O），多硫化物（PS）中间体的溶解和穿梭。这导致生命周期短，库仑/能效低，安全性差和自放电率高。电解质添加剂的使用被认为是解决这些问题的最经济和有效的方法之一。这篇综述概述了正在应用的各种功能性添加剂，目的是为这些吸引人的设备的实际实现开辟新的途径。
