Abstract

Abstract:

Secondary batteries offer the advantages of high energy density and long cycle life, which have provided an effective solution for the storage and use of clean energy. To meet the ever-increasing demand of our society for energy, further in-depth research and development of high-energy-density secondary batteries are imminent. X-ray characterization techniques can provide a comprehensive insight into the research, design, and application of secondary batteries. This review summarizes relevant literature studies published in recent years, with a review of the latest progress and challenges of the X-ray spectroscopy methods in the research of secondary batteries. This review focuses on the technical principles, latest progress, and major scientific challenges of different X-ray characterization techniques, primarily including X-ray photoelectron spectroscopy, X-ray absorption spectroscopy, and resonant inelastic X-ray scattering. The technical characteristics, applicable conditions, and main advantages of different X-ray characterization methods are explained in detail, and the future application of X-ray spectroscopy in the field of secondary batteries is prospected. Comprehensive analysis shows that the X-ray technology provides various advanced characterization techniques that are sensitive and non-destructive to the lattice, electrons, and morphological structure of the electrode materials, and the structure of the electrode materials could be characterized from the macroscopic scale to the microscopic scale, reflecting the corresponding crystal structure and electronic structure evolution, charge compensation mechanism, ion and electron transport, and surface/interface chemical processes of electrode materials. Consequently, X-ray characterization techniques provide technical support for the design of high-performance secondary batteries.
