Conclusion A detailed model of the 18650 cylindrical battery cell that can well predict the mechanical behaviors of the cell under radial compression, indentation, bending, and axial compression is established in this paper. The deformation modes of cells under these loading conditions can be well captured.
By disassembling the battery cell, one may clearly understand the internal structure of the cylindrical battery (Fig. 1). Target 18650 cylindrical LIB is composed of battery casing, jellyroll, winding, and other gaskets, whereas the jellyroll is rolled based on a winding in a separator–cathode–separator–anode sequence (Fig. 1 a).
1. Introduction Lithium-ion batteries (LIBs) are widely used in portable electronic equipment, electrical vehicles, and even aircrafts owing to the environmentally sustainable needs and fast breakthroughs in energy-storage technology.
Therefore, two short-circuit criteria are established based on the mechanical properties of the separator through the detailed model in the scenario of mechanical loading induced internal short circuit, i.e., stress state-based and strain state-based criteria.
Thus, a bilinear isotropic model can be used to describe this material, and the yield stress is used to capture the point when the slope changes. The force of the cathode increases almost linearly with the displacement, such that the linearly elastic model is adopted to describe its mechanical behavior.
