摘要/Abstract

摘要： 理解材料的构-效关系是功能材料领域的永恒话题，在锂离子电池材料的研究中亦是如此。因此可以看到如X射线衍射、中子衍射、核磁共振、X射线电子能谱等结构表征手段被应用于锂离子电池材料的研究中。但是因上述方法对于微观局域结构并不敏感，而给出平均的结构信息。材料的性能往往随微观结构的不同而天差地别，因此获取锂离子电池材料的微观结构信息十分重要。透射电子显微镜具有原子尺度的空间分辨能力，可以获取原子尺度上的结构扭曲和电子结构变化，在锂离子电池材料的研究中起到了至关重要的作用。本文从电子显微学和锂离子电池材料的关系入手，从基本原理和实验方法出发，为相关领域科研人员提供便利。

Abstract: Understanding the structure-function relationship is the eternal topic of functional materials, which is also true for lithium ion battery materials. Thus, various kinds of characterizations, such as XRD, neutron diffraction, NMR, XPS, et al., were used to study lithium ion battery materials. However, these characterization methods are not sensitive to micro-structure, which can only provide global structure information. Micro-structure has huge impact on the properties of materials, so it is important to acquire micro-structure of lithium ion battery materials. Transmission electron microscope can resolve micro-structure at atomic scale, which helped a lot for the study of lithium ion battery materials. This paper is based on the relationship between transmission electron microscopy and lithium ion battery materials in terms of basic principles and experiment methods. We hope this paper can facilitate the research and cooperation for both TEM and lithium ion battery related field.

Key words: transmission electron microscopy, lithium ion battery
