Lithium–sulfur batteries with liquid electrolytes have been obstructed by severe shuttle effects and intrinsic safety concerns. Introducing inorganic solid-state electrolytes into lithium–sulfur systems is believed as an effective approach to eliminate these issues without sacrificing the high-energy density, which determines sulfide-based all-solid-state lithium–sulfur batteries. However, the lack of design principles for high-performance composite sulfur cathodes limits their further application. The sulfur cathode regulation should take several factors including the intrinsic insulation of sulfur, well-designed conductive networks, integrated sulfur-electrolyte interfaces, and porous structure for volume expansion, and the correlation between these factors into account. Here, we summarize the challenges of regulating composite sulfur cathodes with respect to ionic/electronic diffusions and put forward the corresponding solutions for obtaining stable positive electrodes. In the last section, we also outlook the future research pathways of architecture sulfur cathode to guide the develop high-performance all-solid-state lithium–sulfur batteries.

硫化物基全固态锂硫电池:挑战与前景

具有液体电解质的锂硫电池因严重的穿梭效应和本质安全问题而受到阻碍。将无机固态电解质引入锂硫系统被认为是消除这些问题的有效方法,同时又不牺牲高能量密度,这决定了硫化物基全固态锂硫电池。然而,高性能复合硫阴极缺乏设计原理限制了其进一步应用。硫阴极调节应考虑多个因素,包括硫的固有绝缘性、精心设计的导电网络、集成的硫-电解质界面和用于体积膨胀的多孔结构,以及这些因素之间的相关性。在这里,我们总结了调节复合硫正极在离子/电子扩散方面面临的挑战,并提出了获得稳定正极的相应解决方案。在最后一节中,我们还展望了结构硫正极的未来研究路径,以指导高性能全固态锂硫电池的开发。
