Lithium-sulfur (Li-S) technology was identified as a promising candidate to overcome energy density limitations of common lithium-ion batteries given the world-wide abundance of sulfur as a low-cost alternative to state-of-the-art active materials, such as Ni and Co. Li-S cells have received tremendous recognition in recent years, both from a scientific and industrial perspective. However, only few data on adequate multilayer-pouch cell characterization are available so far, and transparent calculations on components require more consideration. Because of the gap of lab cell characterization and prototype cell development, misinterpretations and false expectations are frequently reported, mostly resulting from lithium and electrolyte excess. For the commercialization of the Li-S technology, rapid transfer of new concepts on the prototype cell level is essential. Furthermore, fundamental studies should concentrate on fundamental scientific questions related to the main bottlenecks of Li-S cells: understanding anode and electrolyte degradation phenomena and realistic evaluation of stabilizing interfaces.

锂硫（Li-S）技术被认为是克服普通锂离子电池能量密度限制的有前途的候选者，因为世界范围内大量的硫可以作为最新活性材料的低成本替代品从科学和工业角度看，Li-S电池近年来都获得了广泛认可。但是，到目前为止，关于多层袋式电池特性的数据很少，而且透明的组件计算需要更多的考虑。由于实验室电池表征和原型电池开发之间的差距，经常会出现误解和错误预期，这主要是由于锂和电解质过量造成的。为了使Li-S技术商业化，在原型单元级别快速转移新概念至关重要。此外，基础研究应集中在与Li-S电池主要瓶颈有关的基础科学问题上：了​​解阳极和电解质的降解现象以及稳定界面的实际评估。
