Choosing the appropriate method depends on the application and the type of information required from the battery, such as state of charge (SOC), internal or external defects, state of health (SOH), accessibility, heat generation, and real-time measurements.
Mechanical battery testing of foils, electrodes, separators and cell housing plays a decisive role not only in guaranteeing and further developing quality and performance, but also in ensuring trouble-free production. Tensile, compression, flexure, fatigue and adhesion tests support the realistic characterization of these battery components.
The stress components of an element are obtained from the last frame of the simulation to calculate the pressure and equivalent stress. The (p, σ ¯) pairs of all the elements in the deformed battery cell are plotted in the same coordinate. Here, we investigate two mechanical responses to evaluate the effectiveness of a battery test.
Furthermore, the obtained data serves as the basis for multiphysics simulations. These are used to numerically predict the behavior of the battery, for example in the event of a crash. Tensile tests on battery foil and coated electrodes determine the mechanical strength and elongation.
First, there are still no widely-accepted standards for mechanical tests on battery cells. Second, no general agreements have been made on which model (s) should be used to describe the mechanical behavior. These two gaps are inherently interconnected because tests should serve as the calibration of models and models can explain the tests.
