摘　　要：固态锂硫电池具有高能量密度和高安全性的潜在优势,被认为是最有前景的下一代储能体系之一。虽然固态电解质的应用有效地抑制了传统锂硫电池存在的“穿梭效应”和自放电现象,固态锂硫电池仍面临着多相离子/电子输运、电极/电解质界面稳定性、化学-机械稳定性、电极结构稳定性和锂枝晶生长等关键问题亟待解决。针对以上问题,本综述对近年来固态电解质、硫基复合正极、锂金属及锂合金负极以及电极/电解质界面的研究进行了详细的论述。作为固态锂硫电池的重要组成部分,固态电解质近年来受到了研究者们的广泛关注。本文首先对在锂硫电池中得到广泛应用的聚合物基、氧化物基、硫化物基固态电解质的种类和性质进行了概述,并对其在固态锂硫电池中的最新应用进行了系统的总结。在此基础上,对以单质硫、硫化锂、金属硫化物为活性物质的复合硫正极、锂金属及锂合金负极的反应机理以及面临的挑战进行了归纳和比较,对其解决策略进行了总结和分析。此外,对制约固态锂硫电池性能的电极/电解质界面离子/电子输运以及界面相容性问题及其改性策略进行了系统的阐述。最后,对固态锂硫电池的未来发展进行了展望。All solid-state lithium-sulfur batteries(ASSLSBs)are considered to be one of the most promising next-generation energy storage systems,due to the promises of high energy density and safety.Although the use of solid-state electrolytes could effectively suppress the"shuttle effect"and self-discharge of the conventional liquid lithium-sulfur(Li-S)battery,the commercialization of ASSLSBs has been seriously hampered by the electrolyte degradation,electrode/electrolyte interfacial deterioration,electrochemo-mechanical failure,lithium dendrite growth and electrode pulverization,etc.This paper provides a comprehensive review of recent research progresses on the solid-state electrolytes,sulfur-containing composite cathodes,lithium metal and lithium alloy anodes,and electrode/electrolyte interfaces in ASSLSBs.Specifically,lithium sulfide and metal sulfide as new active cathode materials,and lithium alloy as new anode materials are overviewed and analyzed.In addition,some newly developed interfacial modification strategies for addressing the electrode/electrolyte interfacial challenges are also outlined.Furthermore,an outlook on the future research and development of high-performance ASSLSBs are also presented.
