Several tests are used to evaluate the safety of LIBs, including nail penetration, overcharge, overdischarge, short circuit, and thermal abuse tests 6, 7, 8. The nail penetration test assesses a battery’s internal short circuit mechanism, which is affected by contamination during the manufacturing process or by structural defects.
Neutron imaging overcomes some of the limitations of X-ray tomography for battery studies. Notably, the high visibility of neutrons for light-Z elements, in particular hydrogen and lithium, enables the direct observation of lithium diffusion, electrolyte consumption, and gas formation in lithium batteries.
These techniques can support the study of batteries by identifying the formation of new species and monitoring electrochemical energy stability. However, few works have employed these techniques, which can be used to investigate various materials, including systems beyond lithium-ion technology, in the research of batteries.
Nevertheless, MRI is promising to identify the spatial inhomogeneity across the electrode plane, such as variations in the lithium plating regions on graphite surfaces, which plays a crucial role in the uneven aging process of the battery [ 89, 90 ].
This is particularly important for noise-affected multi-spectral imaging. Furthermore, future studies on lithium batteries will endeavor to use neutron and X-rays simultaneously on the same beamline, as the two radiation types are well suited for combinations of imaging/imaging and imaging/diffraction modes on the same samples.
Among these evaluations, heating tests remain the most prominent source of safety issues. However, information on the phenomena occurring inside batteries during heating has remained inaccessible. In this study, we demonstrate the first in situ neutron imaging method to observe the internal structural deformation of LIBs during heating.
