摘　　要：由于原料丰富、能量密度高和成本低,室温钠-硫电池的应用潜力很大。多硫化钠穿梭效应、硫和硫化钠电子电导率低、钠负极腐蚀和枝晶生长给该电池的实际应用带来了很大挑战。目前,研究人员聚焦于正极材料设计和电解液优化两方面来应对这些挑战。近年来,关于室温钠-硫电池电解液改性的研究众多,但不同改性策略的优化机理和电解液的设计原则有待总结。综述近期室温钠-硫电池电解液的研究。在分析酯类和醚类电解液充放电机理的基础上,回顾并总结酯类、醚类电解液及添加剂优化改性的研究,着重探讨优化改性的具体机理。展望室温钠-硫电池电解液的研究方向。Because of abundant raw materials,high energy density and low cost,room-temperature sodium-sulfur battery has great application potential.The shuttle effect of sodium polysulfide,the low electron conductivity of sulfur and sodium sulfide,sodium anode corrosion and dendrite growth pose great challenges to the practical application of the battery at room temperature.Currently,researchers are focusing on both cathode material design and electrolyte optimization to address these challenges.In recent years,there have been many studies on the modification of the room-temperature sodium-sulfur battery electrolyte,but the optimization mechanism of different modification strategies and the design principles of electrolyte should be summarized.The recent research progress in room-temperature sodium-sulfur battery electrolyte is reviewed.Based on the analysis of charging and discharging mechanism of ester and ether electrolytes,the recent research on optimization modification of ester and ether electrolytes and additives is reviewed,the specific mechanism of optimization modification is emphatically discussed.The research direction of room-temperature sodium-sulfur battery electrolyte is prospected.
