Synchrotron methods to measure internal temperature of lithium-ion batteries

The recent report by Heenan et al. 1 Heenan T.M.M. Mombrini I. Llewellyn A. Checchia S. Tan C. Johnson M.J. Jnawali A. Garbarino G. Jervis R. Brett D.J.L. et al. Mapping internal temperatures during high-rate battery applications. Nature. 2023; 617: 507-512https://doi.org/10.1038/s41586-023-05913-z Crossref PubMed Scopus (6) Google Scholar in Nature demonstrated two advanced synchrotron-based X-ray diffraction (XRD) methods to characterize internal cell temperature along with state-of-charge and mechanical strain within cylindrical lithium-ion cells at high rates. The non-destructive internal temperature evaluation method could further enlighten battery degradation, improve design, and enable innovative management, thus resulting in more durable and safer batteries.
