In this work, a methodolody to model the mechanical behavior of Lithium-ion cells was developed. Volumetric changes in a commercial Lithium-ion cell were experimentally investigated on varying length scales in order to gain insights into the underlying mechanisms. Based on these results, the overall mechanical behavior of a cell was modeled during discharge resulting in a significantly higher accuracy compared to previous publications. This model was then further extended to model local effects in large format Lithium-ion cells.
