Lithium-ion batteries are an integral part of our everyday lives. The demand and technical requirements for battery cells are also constantly increasing. The precise modeling of lithium-ion batteries is therefore an important research topic for a sustainable cell design in terms of performance, safety and aging.

In this thesis, a method for the systematic parameterization of an already implemented model approach for the volume expansion of the active material particles of lithium-ion batteries is to be developed. The model is based on the freely available Python model toolbox "PyBaMM", which allows a direct handling of the theoretical aspects of the selected mechanical submodel due to its modular structure. The volume expansion model is to be validated at the end of the thesis using experimental data.
