"Multiscale Imaging Solutions for Lithium Battery Development"
Lithium battery is an energy storage system with highly complex microstructures covers multiple length scales, namely from millimeter to nanometers. The performance of the battery is dependent on the battery microstructures. Therefore, accurately characterizing the battery microstructure at different length scale, namely from cell level to atomic level, is critical for interpreting battery performance, which ultimately advancing the battery technology. In this talk, I will be discussing the multiscale imaging and analysis solution for lithium battery research.
At cell level, the micro-CT provides a non-destructive diagnostic approach to understand the 3D structure. With (sub) micrometer resolution at cell level, it is employed to track 3D structure evolution at different cycling stages for battery failure analysis. When reaching to electrode and particle level, scanning electron microscopy (SEM) and DualBeamTM technology, also known as focused ion beam–scanning electron microscope (FIB-SEM) technique, are the effective methods for 2D and 3D imaging analysis. SEM provides 2D imaging analysis of the battery morphology with nanometer resolution. Strategies of 2D imaging on different battery materials, including precursor, cathode, anode, and separator will be discussed. In addition to the morphology analysis, a new elemental analysis workflow via ChemiSEMTM will be discussed to demonstrate an efficient approach for elemental identification and quantification for battery electrode analysis.
DualBeam technology is an analytical method combining an ion beam for materials processing and an electron column for imaging to enable 2D and 3D characterization.
Different DualBeam techniques, including Ga+-FIB, Plasma-FIB, and Laser-PFIB technique is demonstrated on different components of battery to collect representative 3D data set for battery structure characterization and degradation mechanism analysis. Furthermore, if the structure at atomic level is of interest, then transmission electron microscope is needed to dive into the atomic structure. A use case of imaging light element, such as lithium atoms, will be discussed in this talk to show the capability of most up to date TEM technology for battery research. In the end, a correlative imaging workflow will be presented to connected data collected with different characterization methods at different length scale for battery failure analysis.
The imaging and analysis techniques enable tremendous analytical capability to accurately characterize battery structure at different length scale. It is expected they will play a more and more important role for battery development in both academia and industrial environment.
