Cylindrical lithium-ion battery cells are a type of rechargeable battery commonly used in a wide range of electronic devices, electric vehicles, and energy storage systems. They are characterized by their cylindrical shape, standardized sizes, and high energy density, making them versatile and suitable for various applications.
For instance, “65” represents a height of 65mm. Fifth Digit: The fifth digit indicates the cylindrical shape of the cell. Typically, it’s “0” for cylindrical cells. By following this naming convention, we can easily identify the size and shape of cylindrical lithium-ion battery cells.
For the modeling of cylindrical lithium-ion batteries, detailed structural models including cathode material, cathode material, diaphragms, and shells can more accurately react to battery deformation and faults, and determine the failure position, but usually require significant computational costs and the model is particularly complex.
However, this limitation has not been a central concern in the present study, as cylindrical lithium-ion batteries primarily exhibit deformation in only two directions. The focus of this paper is specifically on the most critical direction of the battery, during high-impact vehicle crashes, where lateral forces dominate.
We report on modeling mechanical response of cylindrical lithium-ion battery cells that are commonly used in automotive applications when subjected to impact testing. The developed homogenized model that accurately captures mechanical response of a cell to lateral crash is reported.
