开发先进的储能系统对于满足电动汽车、便携式设备和可再生能源收获不断增长的需求至关重要。锂硫（Li-S）电池具有比能量密度高、原材料成本低、对环境友好等优点，有望成为下一代电池。然而，Li-S电池的实际应用存在许多障碍，例如硫的电绝缘性质，锂插入期间的体积膨胀，以及引起电池性能严重下降的可溶性多硫化物中间体的穿梭。本文综述了锂硫电池多功能隔膜/中间层的研究进展。引入具有意想不到的多功能的多功能隔膜/夹层有利于更好的硫利用率、有效的多硫化物扩散抑制和阳极保护。已经提出了具有离子选择性/导电聚合物、sp（2）和多孔碳、金属氧化物改性的隔膜以及互连的自支撑纳米碳、微米/介孔碳和其他导电夹层的多功能隔膜系统。生物质衍生材料也被包括作为先进的锂硫电池的中间层。这些具有多功能隔板/夹层的新型Li-S电池配置特别适用于具有高容量、高稳定性和高倍率性能的Li-S电池。讨论了高性能隔膜/中间层及其在下一代锂硫电池中的应用。应进一步探索工作隔膜/中间层在实际Li-S电池中的作用的新见解，以获得基于多电子转换反应的储能装置的先进组件的原理和工艺。(C)2015 Elsevier B.

The development of advanced energy storage systems is of crucial importance to meet the ever-growing demands of electric vehicles, portable devices, and renewable energy harvest. Lithium-sulfur (Li-S) batteries, with the advantages in its high specific energy density, low cost of raw materials, and environmental benignity, are of great potential to serve as next-generation batteries. However, there are many obstacles towards the practical application of Li-S batteries such as the electrical insulating nature of sulfur, the volume expansion during lithium insertion, and the shuttle of soluble polysulfide intermediates that induces severe degradation of the cell performance. In this review, the progresses of multifunctional separators/interlayers in Li-S batteries are highlighted. The introduction of multi-functional separators/interlayers with unexpected multiple functionalities is beneficial for better sulfur utilization, efficient polysulfide diffusion inhibition, and anode protection. Multi-functional separator system with ion selective/electrical conductive polymer, sp(2) and porous carbon, metal oxide modified separators, as well as interlinked free-standing nanocarbon, micro/mesoporous carbon, and other conductive inter layers have been proposed. The biomass derived materials was also included as interlayer for advanced Li-S batteries. These novel Li-S cell configurations with multi-functional separators/interlayers are especially suitable for Li-S batteries with high capacity, high stability, and high-rate performance. The opportunities of high-performance separators/interlayers and their applications in next-generation Li-S batteries were also involved. New insights on the role of working separators/interlayers in practical Li-S cells should be further explored to obtain the principle and process for advanced components for energy storage devices based on multi-electron conversion reactions.
