In‐situ transmission electron microscopy implemented with a microelectromechanical system (MEMS) heating device is invented by to investigate the electrochemical reactions of high temperature Na‐S batteries (reported by Yongfu Tang, Liqiang Zhang, Jianyu Huang and co‐workers in article number 2100846). The evolution of transient polysulfides is revealed. The studies provide not only new understanding to polysulfide electrochemistry but also critical strategies to boost performance of high temperature Na‐S batteries for large‐scale energy storage applications.
