Safety of lithium-ion batteries under mechanical loadings is currently one of the most challenging and urgent issues facing in the Electric Vehicle (EV) industry. The architecture of all types of large-format automotive batteries is an assembly of alternating layers of anode, separator, and cathode.
Deformation and failure of Li-ion batteries can be accurately described by a detailed FE model. The DPC plasticity model well characterizes the granular coatings of the anode and the cathode. Fracture of Li-ion batteries is preceded by strain localization, as indicated by simulation.
Lightweight Al hard casings have presented a possible solution to help address weight sensitive applications of lithium-ion batteries that require high power (or high energy). The approaches herein are battery materials agnostic and can be applied to different cell geometries to help fast-track battery performance improvements. 1. Introduction
This is a clear candidate for the future research. We believe that the present detailed computational model will be found useful in the design process of the new generation of batteries and at the same time, will prove to be an important new computational tool for assessing the safety of lithium-ion batteries against mechanical loading.
Finally, mechanical behaviors of the entire Lithium-ion batteries were simulated numerically under dynamic crushing conditions. The study is anticipated to gain new understanding in dynamic characteristics of LIB, thereby providing guideline for design of LIB packs/modules.
Lithium-ion batteries (LIB) are currently one of the most promising energy storage technologies with a range of applications [ 1, 2, 3 ]. Conventionally, batteries employ organic liquid-based electrolytes which have high Li-ionic conductivity (~ 10 −2 to 10 −3 S cm −1) and excellent wettability at the electrode–electrolyte interfaces [ 4, 5 ].
