Lithium-ion sulfur batteries as a new energy storage system with high capacity and enhanced safety have been emphasized, and their development has been summarized in this review. The lithium-ion sulfur battery applies elemental sulfur or lithium sulfide as the cathode and lithium-metal-free materials as the anode, which can be divided into two main types. One is anode-type, where elemental sulfur is applied as the cathode, and the anode provides lithium ions. The other one is cathode-type, where lithium sulfide as the cathode provides lithium ions, and lithium-metal-free materials (e.g., graphite, silicon/carbon) function as the anode. Recently, some new lithium-ion sulfur battery systems have also been proposed, and are discussed in this review as well. The lithium-ion sulfur batteries not only maintain the advantage of high energy density because of the high capacities of sulfur and lithium sulfide, but also exhibit the improved safety of the batteries due to a non-lithium-metal in the anode. This review paper aims to track the recent progress in the development of lithium-ion sulfur batteries and summarize the challenges and the approaches for improving their electrochemical performances, including the lithiation methods to prepare lithium-metal-free anodes in anode-type lithium-ion sulfur batteries and the lithium sulfide cathode modification approaches in cathode-type lithium-ion sulfur batteries. Furthermore, the challenges and perspectives for future research and commercial applications have also been enumerated.

新型大容量安全储能系统：锂离子硫电池

锂离子硫电池作为一种具有高容量和增强安全性的新储能系统已得到强调，其发展已在本综述中进行了概述。锂离子硫电池以元素硫或硫化锂为阴极，无锂金属材料为阳极，可分为两种主要类型。一种是阳极型，其中元素硫被用作阴极，而阳极提供锂离子。另一种是阴极型，其中硫化锂作为阴极提供锂离子，而无锂金属的材料（例如，石墨，硅/碳）作为阳极。最近，还提出了一些新的锂离子硫电池系统，并且在本综述中也进行了讨论。锂离子硫电池不仅由于硫和硫化锂的高容量而保持了高能量密度的优点，而且由于阳极中的非锂金属而表现出改进的电池安全性。这篇综述文章旨在追踪锂离子硫电池发展的最新进展，并概述提高其电化学性能的挑战和方法，包括锂化方法以制备阳极型锂离子电池中的无锂金属阳极阴极型锂离子硫电池中的硫电池和硫化锂阴极改性方法。此外，
