Abstract In engineering applications such as electric vehicles and energy storage systems, the structural safety of cylindrical lithium-ion batteries is crucial, especially under external impact or compressive loads that may induce deformation or damage, affecting overall safety performance.
At present, there have been many breakthroughs in the research of homogenization models. Xia et al. and Wang et al. respectively established a homogenization model of the cylindrical lithium-ion battery, considering the material as anisotropy and the influence of SOC and dynamic effect.
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.
