Calendering is an essential step to densify the porous structure of lithium-ion battery electrodes, enhancing the energy density and mechanical properties. This process involves mechanical interactions among particles and between particles and current collector.
The gradually concentrated indentation from the punch tip and the resistance from the floor panel cause compression and shortening of the cells exactly above the punching tip. It can also be noticed from the last frame in Fig. 16, that the upward moved battery cell finally punctured the floor panel.
The punching process after the armor plate perforation, the ensuing crack propagation of the armor plate as well as the local deformation modes of individual battery cells are clearly predicted by the global modeling.
Shortening of the battery cells above the punch tip vs. the indentation distance of the punch is shown in Fig. 17, in which three different stages of the battery cell deformation can be more clearly distinguished. At the first stage, the battery is shortened slightly.
Deformation and fracture of battery without CFRP layer During TR, the battery shell swells due to the increase of internal pressure P and temperature T. The deformation ε consists of two parts: the deformation ε p produced by internal pressure and the deformation ε t introduced by the thermal expansion effect.
Before the armor plate perforation the peak force in the dynamic case is much higher at the same displacement. Therefore, in the dynamic case, perforation of the armor plate occurs relatively early with respect to the indentation distance of the punch tip, also configuring earlier threats to the battery cells.
Crack propagation in the armor plate goes through circumferentially around the punch tip, leaving a cap on the punch tip and a hole in the armor plate. Further indentation of the punching object enlarges the diameter of the punctured hole and deforms the plastic enclosure of the battery module.

Généralement, une batterie dure entre 5 et 15 ans. Ces chiffres varient en fonction de plusieurs éléments : Le type de batterie: celles en plomb ont une durée de vie plus courte que celles en lithium par exemple. L''utilisation: plus une batterie sera chargée et déchargée (ce qu''on appelle un cycle), moins sa durée de vie sera longue.

Efficiency of the thermal design can be further increased by using perforated battery compartments. Effluents generated by the battery cells enter the hollow guideways formed within the battery pack through these perforations. The guideways direct the effluents to a gas exhaust nozzle, which releases it out of the battery pack
