Strain rate dependent plasticity of lithium-ion pouch cells: Experiments and simulations

The safety of electric vehicles under crash event depends on the mechanical behavior of Lithium-ion cells under large deformation at high strain rates. Here, an extensive experimental campaign is performed on large-format pouch cells under out-of-plane indentation with two indenter shapes and speeds ranging from a few millimeters per minute up to ten meters per seconds, spanning six decades of strain rates. It reveals that the displacement at...
