张华民教授团队和孙学良教授团队EER最新综述︱锂-硫电池结构设计：从基础研究到实际应用

最新综述：锂–硫（Li–S）电池是最具潜力的能量存储设备之一，其能量密度高于最先进的锂离子电池。由于其理论能量密度高、成本效益好，过去几年Li–S电池受到高度重视，取得了长足发展。然而，基础研究与实际应用之间难以逾越的鸿沟是锂–硫电池商业化的主要障碍。本综述从工程角度深入洞悉并讨论了Li–S电池应用的合理结构设计和参数。首先调查了影响质量能量密度、体积能量密度和成本的各种参数（硫负载量，电解质/硫（E/S）比，放电容量，放电电压，锂过量百分比，硫含量等）。通过比较和分析近期有关Li–S的文献进行信息统计，本文梳理了Li–S技术的不足，并提供了克服主要问题的可行策略。最后讨论了锂–硫电池工程的发展方向和前景。

Structural Design of Lithium–Sulfur Batteries: From Fundamental Research to Practical Application

 Abstract: Lithium–sulfur (Li–S) batteries have been considered as one of the most promising energy storage devices that have the potential to deliver energy densities that supersede that of state-of-the-art lithium ion batteries. Due to their high theoretical energy density and cost-effectiveness, Li–S batteries have received great attention and have made great progress in the last few years. However, the insurmountable gap between fundamental research and practical application is still a major stumbling block that has hindered the commercialization of Li–S batteries. This review provides insight from an engineering point of view to discuss the reasonable structural design and parameters for the application of Li–S batteries. Firstly, a systematic analysis of various parameters (sulfur loading, electrolyte/sulfur (E/S) ratio, discharge capacity, discharge voltage, Li excess percentage, sulfur content, etc.) that influence the gravimetric energy density, volumetric energy density and cost is investigated. Through comparing and analyzing the statistical information collected from recent Li–S publications to find the shortcomings of Li–S technology, we supply potential strategies aimed at addressing the major issues that are still needed to be overcome. Finally, potential future directions and prospects in the engineering of Li–S batteries are discussed.
