讲座摘要/Abstract:

Energy conversion and storage are an important enabling technology for renewable energy, portable electronics, and modern transportation systems. However, the dynamic changes of a reaction need to be visualized directly at the atomic scale to provide important feedback to build long-live and low-cost batteries and catalysts. In my talk, I will focus on the electron microscopy technique developments (in-situ TEM and cryo-TEM) to address the challenges of imaging a dynamically changing system and electron-sensitive energy-related materials. The advances in the aberration-corrected scanning / transmission electron microscopy have enabled the study of physical structure, chemical composition, bonding of complicated chemical substance at the atomic scale and in three dimensions. State of the art in-situ microscopy method opens the door for visualizing the dynamic surface reconstructions of catalysts at work and study of the dynamic changes of the electrodes/electrolyte during electrochemical cycling. Last, I want to share my research progress in the development ultralow-dose cryo-TEM technique to study sensitive batteries materials to reveal their unknown functional mechanism.
