Applications and Challenges of Advanced Characterization Techniques in All-Solid-State Lithium-Sulfur Battery Cathodes
All-solid-state lithium-sulfur batteries (ASSLSBs) are regarded as one of the most promising next-generation energy storage systems due to their ultrahigh theoretical energy density (2600 Wh/kg) and enhanced safety. Current bottleneck issues primarily stem from the sluggish redox kinetics and mechanical degradation of sulfur-based cathodes in solid-state systems. Therefore, developing advanced characterization techniques to elucidate the behavior of sulfur cathodes in solid-state configurations is crucial for optimizing battery design and enhancing performance. This review summarizes recent research progress in advanced characterization technologies for cathode development in all-solid-state Li-S batteries. Through representative case studies, it comprehensively explores how X-ray, electron, optical, and other emerging techniques reveal the sluggish kinetics and degradation mechanisms of sulfur-based cathodes, providing guidance for high-performance cathode design. Finally, the article prospects future development directions of characterization technologies in solid-state Li-S battery cathodes and summarizes current challenges, offering valuable insights and references for future research endeavors.
