Batteries that extend performance beyond the intrinsic limits of Li-ion batteries are among the most important developments required to continue the revolution promised by electrochemical devices. Of these next-generation batteries, lithium sulfur (Li–S) chemistry is among the most commercially mature, with cells offering a substantial increase in gravimetric energy density, reduced costs and improved safety prospects. However, there remain outstanding issues to advance the commercial prospects of the technology and benefit from the economies of scale felt by Li-ion cells, including improving both the rate performance and longevity of cells. To address these challenges, the Faraday Institution, the UK’s independent institute for electrochemical energy storage science and technology, launched the Lithium Sulfur Technology Accelerator (LiSTAR) programme in October 2019. This Roadmap, authored by researchers and partners of the LiSTAR programme, is intended to highlight the outstanding issues that must be addressed and provide an insight into the pathways towards solving them adopted by the LiSTAR consortium. In compiling this Roadmap we hope to aid the development of the wider Li–S research community, providing a guide for academia, industry, government and funding agencies in this important and rapidly developing research space.

将性能扩展到锂离子电池固有极限之外的电池是继续电化学设备所承诺的革命所需的最重要的发展之一。在这些下一代电池中，锂硫 (Li-S) 化学是商业上最成熟的电池之一，电池的重量能量密度显着增加，成本降低，安全前景改善。然而，要推进该技术的商业前景并从锂离子电池感受到的规模经济中受益，仍然存在突出的问题，包括提高电池的倍率性能和寿命。为了应对这些挑战，英国独立的电化学储能科学与技术研究所法拉第研究所，于 2019 年 10 月启动了锂硫技术加速器 (LiSTAR) 计划。 该路线图由 LiSTAR 计划的研究人员和合作伙伴撰写，旨在突出必须解决的突出问题，并提供对解决这些问题的途径的见解LiSTAR 财团。在编制此路线图时，我们希望帮助更广泛的 Li-S 研究社区的发展，为学术界、工业界、政府和资助机构在这个重要且快速发展的研究领域提供指导。
