Advanced (scanning) transmission electron microscopy ((S)TEM) techniques have been intensively applied to study the materials for energy storage. With/Combining different TEM techniques, including in-situ TEM and diffraction, HAADF-STEM, and STEM-electron energy-loss spectroscopy, researchers are able to probe local structural and chemical information of electrode materials. The first part of this talk will focus on using in-situ and analytical TEM to characterize the oxide electrode materials of lithium ion batteries [1-4]. The dynamical process of the redox reaction revealed by in-situ TEM may help us to understand how reaction pathways and defects affect the batteries’ kinetic properties. The second part of this talk highlights the importance of advanced TEM for developing electrocatalysts, in combination of electrochemical characterization and first principles calculations [5-8]. We will discuss the recent progresses in the Pt-based nanocatalyst for proton exchange membrane fuel cells, especially on how the strain affecting the surface electronic structure and how to tune the synthesis process to obtain the high efficient catalysts.
