1. Introduction Cylindrical lithium ion battery cells have been a major power source for Electric Vehicles like Tesla Model S. The vertical configuration of these cells in the floor mounted battery packs make them prone to axial deformation in case of a ground impact.
Among all cell components, the battery shell plays a key role to provide the mechanical integrity of the lithium-ion battery upon external mechanical loading. In the present study, target battery shells are extracted from commercially available 18,650 NCA (Nickel Cobalt Aluminum Oxide)/graphite cells.
Safety of Li-ion cells is perhaps the main factor behind the efforts to develop suitable deformation and failure models. Batteries may also fail under thermal abuse (overheating) or electrical abuse (overcharging). This paper is concerned only with mechanical abuse, which is a relatively new topic.
The cylindrical lithium-ion battery has been widely used in 3C, xEVs, and energy storage applications, as the first-generation commercial lithium-ion cells. Among three types of lithium-ion cell format, the cylindrical continue to offer many advantages compared to the prismatic and pouch cells, such as quality consistency and cost.
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.
