Advanced Characterization Techniques for Li-S Batteries

Since the creation of their first prototype in the 1960s, lithium-sulfur (Li-S) batteries have been anticipated to be a viable high-energy-density secondary battery system. By addressing the issues at the lab-level model systems, significant progress has been made over the past 10 years in promoting the performance of Li-S batteries. Li-S battery applications are receiving more attention; however, the bottleneck is being caused by brand-new difficulties at realistic cell sizes. In this review, we first introduce the lithium-sulfur batteries and describe their principle. Then, we elaborate all the recent advances and finally concluded along with future research objectives.
