The lithium sulfur battery has a high theoretical capacity of 1675 mAh g⁻¹, and is cheap and environmentally friendly, which make it a very promising secondary battery. However, its cycling stability cannot meet the requirements of industrialization due to the shuttle effect caused by the dissolution of polysulfides in the discharge process, the insulating nature of sulfur and the volume expansion of the sulfur cathode. Graphene has an excellent electrical conductivity, an extremely large specific surface area, good mechanical flexibility, and thermal and chemical stability, making it and its derivatives promising candidates to modify both the electrodes of an all-solid-state lithium-sulfur battery and the separator. The mechanisms, by which graphene and its derivatives inhibit the shuttle effect are summarized. The graphene network is very favorable for improving electron transfer rate, limiting volume expansion and facilitating lithium ion migration in the sulfur cathode of all-solid-state lithium-sulfur batteries. As modifiers of the separator, the hexagonal layer structure of graphene and its derivatives forms channels for lithium-ion transport and sulfur capture. Development strategies for using graphene and its derivatives in lithium-sulfur batteries are proposed.

锂硫电池具有1675 mAh g ^-1的高理论容量，并且便宜且环保，这使其成为非常有前途的二次电池。但是，由于放电过程中多硫化物的溶解，硫的绝缘性和硫阴极的体积膨胀引起的穿梭效应，其循环稳定性不能满足工业化的要求。石墨烯具有优异的导电性，非常大的比表面积，良好的机械柔韧性以及热和化学稳定性，因此石墨烯及其衍生物有望成为修饰全固态锂硫电池和隔离膜的电极的候选材料。总结了石墨烯及其衍生物抑制穿梭效应的机理。石墨烯网络对于提高电子传输速率非常有利，限制体积膨胀并促进锂离子在全固态锂硫电池的硫阴极中迁移。作为隔膜的改性剂，石墨烯及其衍生物的六边形层结构形成了锂离子传输和硫捕获的通道。提出了将石墨烯及其衍生物用于锂硫电池的发展策略。
