报告摘要：

Lithium ion batteries (LIBs) have become a rapidly growing energy storage technology. The cathode materials are considered to be the performance-limiting factor in research designed to increase cell energy and power density. During the cathode materials exploration, the advanced synchrotron-based characterization techniques, such as high-resolution synchrotron X-ray diffraction (HRXRD), in situ high-energy synchrotron X-ray diffraction (HEXRD), and in situ X-ray absorption spectroscopy (XAS), provide novel and powerful tools for exploring the structure evolution of battery materials. Herein, I will introduce how synchrotron-based techniques could be utilized for phase identification, fundamental study of structure dynamics, reaction mechanism, and doping mechanism during the cathode material exploration. Then, the presentation will be centered on the fundamental studies of V₂O₅ and LiCoO₂ as the cathode materials for Li-ion batteries. Typically, the in-depth investigation of phase transformation behavior in V₂O₅-based and LiCoO₂ in Li-ion batteries has been studied using advanced in-situ synchrotron techniques.
