This model offers a sectional view, illustrating the stress distribution within the lithium-ion battery (LIB) cell and the base. Notably, the indentation force caused the cell to bend, acquire a concave shape, and separate from the steel platen underneath, aligning with the experimental findings.
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.
First, though, Wierzbicki says engineers need to understand the mechanical properties and physical limits of existing batteries. Now he and MIT postdoc and MIT Battery Consortium co-director Elham Sahraei have studied the resilience of cylindrical lithium-ion batteries similar to those used to power the Tesla Roadster and other electric vehicles.
At pack and system level, crash test is applied to assess the mechanical and safety performance of the battery. Different collision angles and speeds are selected for testing to determine the limits of the battery subjected to collision impact loads, which in turn guides the development and design of the entire vehicle.
