Customer ServiceBatteries subjected to compression develop a distinct pattern of folds and kinks (Wang, Simunovic, Maleki, Howard, & Hallmark, 2016) often observed in some granular materials, while on the other hand, the strength of the battery structure is significantly greater than that of natural granular media due to the existence of the current collectors.
It can be concluded that the localization occurs first with no need of the foil fracture to initiate the failure of the battery. As soon as localization occurs, there is a rapid increase of the equivalent strain leading to the fracture of the aluminum foils and then of the copper foils.
The onset of the failure of batteries is understood here as the fracture of the aluminum foil, which triggers the global crack formation. The global geometry of the pouch cell is defined by the radius of the cylindrical indenter and the thickness of the cell . The hardening curve of the aluminum foil is approximated by the power law .
The architecture of all types of large-format automotive batteries is an assembly of alternating layers of anode, separator, and cathode. The anode is composed of a very thin copper foil double-side coated with graphite powders, while the cathode is an aluminum foil with the active material coating.
The components of the battery under the punch develop biaxial loading with initial compression in the through-thickness direction and the superposed increasing tension in the in-plane direction. The trajectory of the stress state for the two critical locations under the punch are plotted in Fig. 14 from the FE simulation.
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.
