Development of advanced SIBs requires a clear understanding of structures and kinetic/dynamic process occurred in the cells during the charging/discharging process. In situ transmission electron microscopy (TEM) is a powerful tool for direct visualizing the phase transitions, morphological and structural evolutions of the electrodes during the electrochemical reaction process. Herein, we summarize the state-of-the-art in situ TEM studies on SIBs with a specific focus on real-time observations of the electrochemical behaviors of battery materials. This review emphasizes the necessity of in situ TEM for elucidating fundamental issues regarding reaction mechanism, phase transformation, structural evolution and performance degradation of SIBs. Finally, critical challenges and emerging opportunities for in situ TEM research of SIBs are discussed.
