摘 要：
锂硫电池具有理论比容量高(1675 m Ah·g~(-1))、能量密度高(2600 Wh·kg~(-1))、环境友好、价格低廉等性质,是一种高性能的新型储能电池。这些性能使其在电动汽车和便携式设备领域具有重要意义。然而,快速的容量衰减以及较差的循环性能,使锂硫电池还达不到商业应用的要求。本文全面总结了锂硫电池的最新研究进展,详细阐述了锂硫电池的正极、电解质、隔膜以及负极保护,分析了现有锂硫电池存在的缺陷和问题。最后,对锂硫电池未来的发展方向进行了展望。

Abstract:
Lithium-sulfur batteries are considered to be rather latest and high-performance storage batteries due to their high theoretical specific capacity (1675 mAh·g-1), high energy density (2600 Wh·kg-1), environmental friendliness, low cost, and safety. These features make them important in the field of mobile electric vehicles and portable devices. However, because of rapid capacity attenuation with poor cycle and rate performances, these batteries are far from ideal for commercial applications. This paper reviews the entire and latest studies in lithium-sulfur batteries. Cathodes, electrolyte, separators, and anodes protection are introduced in detail. The existing lithium-sulfur batteries defects and problems are analyzed. Finally, we provide some insights into the future direction and prospects of lithium batteries.
