锂硫电池是在不久的将来最有前途的电化学储能装置之一。特别是硫作为阴极材料的低价格和丰富的可用性以及与最先进的锂离子技术相比的高理论容量是吸引人的特点。尽管在过去几年中取得了重大的研究成果，但基本的（电）化学问题仍然没有得到解答。这篇综述阐述了与锂硫电池相关的十个关键问题，并对目前的研究进行了批判性评估。硫碳复合阴极是一个特别的焦点，但它与电池中其他硬件组件（如电解质和阳极）的复杂相互作用，需要对其他电池组件进行关键的讨论。现代的原位表征方法非常适合于阐明每个组件的作用。这篇文章并不试图总结所有最近发表的数据，而是基于最近的研究成果对锂硫电池进行了批判性的概述。
Lithium-sulfur batteries are among the most promising electrochemical energy storage devices of the near future. Especially the low price and abundant availability of sulfur as the cathode material and the high theoretical capacity in comparison to state-of-the art lithium-ion technologies are attractive features. Despite significant research achievements that have been made over the last years, fundamental (electro-) chemical questions still remain unanswered. This review addresses ten crucial questions associated with lithium-sulfur batteries and critically evaluates cur-rent research with respect to them. The sulfur-carbon composite cathode is a particular focus, but its complex interplay with other hardware components in the cell, such as the electrolyte and the anode, necessitates a critical discussion of other cell components. Modern in situ characterisation methods are ideally suited to illuminate the role of each component. This article does not pretend to summarise all recently published data, but instead is a critical overview over lithium-sulfur batteries based on recent research findings.
