AI Customer ServiceAccording to studies, battery mechanical failures account for almost one-third of electric vehicle safety accidents [ 4 ], with deformation caused by scratches or collisions of the battery pack being a common culprit. This can lead to destructive failure of the battery, resulting in a burning or exploding electric vehicle [ 5, 6, 7, 8 ].
Catastrophic failures often result in venting of the electrolyte, fire, or explosion. This is usually due to an overstress condition where the battery is abused or operated outside of its recommended voltage, current, or temperature limits , , .
On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly. Catastrophic failures often result in venting of the electrolyte, fire, or explosion.
Battery modules of new energy vehicles are frequently exposed to dynamic impacts during traffic accidents. However, current research on the mechanical safety of prismatic lithium-ion batteries (PLIBs) primarily focuses on quasi-static states, and the failure mechanism of batteries under dynamic impact remains incompletely understood.

The load corresponding to these points is the destructive force of the PLIB, and it can be seen that the destructive force when the battery fails under dynamic loading conditions is lower than that under low-velocity conditions, which is consistent with the results of the 18650 batteries in reference [ 35 ].
