可再生技术，特别是电动汽车革命，对锂离子电池性能的提高产生了巨大的压力。为了满足日益增长的市场需求，面临着提高能量密度、延长循环寿命和提高安全性的挑战。为了解决这些问题，深入了解电池材料在工作条件下的物理和化学变化，对于将降解过程与其材料性质和电化学特征的来源联系起来至关重要。基于原位和操作同步加速器的X射线技术为电池材料研究提供了强大的工具，使人们能够深入了解循环过程中的结构演变、氧化还原过程和传输特性。本文对基于同步辐射的原位X射线衍射法进行了详细的讨论，重点介绍了提高空间和时间分辨率的最新进展。这里回顾的实验方法包括单元设计和材料，以及光束线实验装置的细节。最后，讨论了电池技术未来的挑战和机遇。
Renewable technologies, and in particular the electric vehicle revolution, have generated tremendous pressure for the improvement of lithium ion battery performance. To meet the increasingly high market demand, challenges include improving the energy density, extending cycle life and enhancing safety. In order to address these issues, a deep understanding of both the physical and chemical changes of battery materials under working conditions is crucial for linking degradation processes to their origins in material properties and their electrochemical signatures. In situ and operando synchrotron-based X-ray techniques provide powerful tools for battery materials research, allowing a deep understanding of structural evolution, redox processes and transport properties during cycling. In this review, in situ synchrotron-based X-ray diffraction methods are discussed in detail with an emphasis on recent advancements in improving the spatial and temporal resolution. The experimental approaches reviewed here include cell designs and materials, as well as beamline experimental setup details. Finally, future challenges and opportunities for battery technologies are discussed.
