July 2023 - The recent report by Heenan et al.1 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.
