<p>The global push toward environmental sustainability has positioned lithium-ion batteries (LIBs) as the dominant power source for numerous applications due to their high energy density. As a result, the aviation industry is increasingly exploring electrification as a potential solution to reduce emissions and mitigate climate change. However, the widespread adoption of batteries is limited by safety concerns arising from potential failures. To advance lithium-ion battery safety and pave the way for a more sustainable aviation future, a comprehensive understanding of these failure mechanisms is crucial. This paper highlights the critical role of advanced finite element analysis (FEA) simulations in modeling the behavior of SBs under abuse conditions. These simulations can be instrumental in predicting the occurrence of internal short circuits, a paramount safety concern. An abuse load scenario is simulated on structural batteries, both integrated and standalone, using the commercial LS-DYNA solver. The resulting data have been analyzed to emphasize the importance of multiphysics-based design tools in developing safer and more multifunctional structures.</p>
