In the present work, lithium-ion battery cathodes and battery half-cells are numerically investigated. Of main interest is the influence of the calendering of an electrode during its manufacture on the mechanically induced changes in the microstructure and the resulting performance characteristics of a cell. In particular, the influence of varying particle shape and plastic material properties is considered.

The focus of this work is on the modelling of the degradation behaviour of conventional lithium-ion cells with graphite/NMC electrodes in conjunction with electrolytes based on LiPF6 in organic solvents. The potential for improvements of parameterization methods dealing with physical-chemical aging effects and simulation studies for optimization of the battery lifetime is shown. In the process of model parameterization mostly data-based as well as non-invasive analysis methods are used.
