Transmission electron microscopy of lithium ion battery materials

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.
