摘　　要：以金属锂为负极、单质硫为正极活性物质的锂硫电池的理论比能量为2600 W·h/kg,是全部由固态活性物质组成的、比能量最高的一种二次电池。硫和锂储量丰富、成本低廉。采用固态电解质的全固态锂硫电池能够明显提高电池的安全性并有望提高电池的循环性能,已成为储能电池技术研究和开发的热点。本文综述了近年国内外的全固态锂硫电池的研究进展,从固体电解质、硫基正极、锂基负极、"电极/电解质"界面、固态电池制备方法等方面分别进行了综述,并对全固态锂硫电池未来的发展方向和发展前景进行展望。Lithium-sulfur （Li-S） battery employing lithium as the anode and sulfur as the cathode possesses the highest theoretical energy density of 2600 W＇h＇kg-1 among the rechargable batteries consisted by the solid-state active materials. Sulfur and lithium resources are also abundant and low cost. To replace the organic liquid electrolyte by the solid electrolyte, the all-solid-state battery systems are expected to solve the safety issues and improve the cycling stability of Li-S batteries. It is becoming the hot topic in reaseach and development of rechargeable batteries. This paper presents a comprehensive review of the progress of all solid-state Li-S batteries in recent years, including solid electrolytes, sulfur-based cathodes, lithium-based anodes, electrode/electrolyte interface, and cell fabrication methods. The developments of all solid-state Li-S batteries are prospected as well.
