In this study, a heterogeneous finite element model was developed in LS-DYNA to investigate lateral impact on 6P cylindrical lithium-ion battery cells manufactured by Johnson Controls Inc. The results were compared to those from a homogenized model previously reported by the authors and also experimental data and showed a good agreement.

Simplification of the full homogenized model of Lithium-ion cell is done, and a comparison with simplified models based on the P2D model is made. Elevated energy density is a prime requirement for many lithium-ion battery (LIB) applications, including electric vehicles (EVs). At the cell level, the enhanced energy density of LIBs is
Lithium−sulfur (Li−S) batteries are ideal energy storage devices due to their high energy density (2600 Wh kg −1), but polysulfide shuttling and lithium dendrite growth seriously preclude their practical application.Herein, a multifunctional layer composed of MnO, MnWO 4 and carbon black (CB) is constructed to modify the polypropylene separator (MnO-MnWO 4
