摘要 近年来,高比能锂-硫电池作为最具前景的新能源储存装置之一引起了人们的广泛关注。然而,在该电池体系中,中间产物聚硫化物的溶解造成的穿梭效应会明显降低电池的循环性能和硫利用率,严重阻碍锂-硫电池的推广应用。综述了近年来石墨烯和石墨烯基复合自支撑中间层材料在锂-硫电池中的应用,例如,通过物理或化学限域的方法减缓多硫化物的穿梭并改善锂-硫电池电化学性能等,并对石墨烯基复合自支撑中间层材料未来在锂硫电池中的实际应用进行了展望。

Abstract: In recent years, as one of the most promising sustainable energy storage devices, high-energy-density lithium-sulfur batteries have attracted widespread attention. However, the shuttle effect caused by the dissolution of intermediate products polysulfides during cycling can significantly influence the cycling performance and sulfur utilization rate of lithium-sulfur batteries, which seriously hinders their practical application and commercialization. Herein, this review summarizes the state-of-the-art of application of graphene and graphene-based self-supporting interlayer composite materials in recent years in lithium-sulfur batteries. For instance, physical or chemical confinement methods could be used to retard the shuttle effect of polysulfides and improve the electrochemical performance of lithium-sulfur batteries. The development direction and prospect of practical application of graphene-based self-supporting interlayer composite materials in lithium-sulfur batteries are also predicted and forecasted.
