Electrolytes, which are a key component in electrochemical devices, transport ions between the sulfur/carbon composite cathode and the lithium anode in lithium–sulfur batteries (LSBs). The performance of a LSB mostly depends on the electrolyte due to the dissolution of polysulfides into the electrolyte, along with the formation of a solid–electrolyte interphase. The selection of the electrolyte and its functionality during charging and discharging is intricate and involves multiple reactions and processes. The selection of the proper electrolyte, including solvents and salts, for LSBs strongly depends on its physical and chemical properties, which is heavily controlled by its molecular structure. In this review, the fundamental properties of organic electrolytes for LSBs are presented, and an attempt is made to determine the relationship between the molecular structure and the properties of common organic electrolytes, along with their effects on the LSB performance.

有机电解质的结构-性能关系及其对Li / S电池性能的影响

电解质是电化学设备中的关键组件，它在锂硫电池（LSBs）中的硫/碳复合阴极和锂阳极之间传输离子。LSB的性能主要取决于电解质，这是由于多硫化物溶解到电解质中，以及形成了固体-电解质中间相。在充电和放电过程中，电解质及其功能的选择非常复杂，涉及多个反应和过程。对于LSB，选择合适的电解质（包括溶剂和盐）在很大程度上取决于其物理和化学性质，而该性质受到其分子结构的严格控制。在这篇综述中，介绍了用于LSB的有机电解质的基本特性，
