Aim of the BMBF Project: MULTIBAT
The development of efficient mathematical methods for the modeling of multi-phase and multi-scale processes in lithium-ion batteries.
The Modeling Involves:
- the stochastic structure modeling of porous electrodes for the generation of parametrized dynamic structure models based on imaging data,
- the mathematical modeling of the underlying physical and electrochemical processes by coupled systems of partial differential equations,
- their efficient high-resolution simulation with modern adaptive multiscale methods,
- as well as the model order reduction of high-dimensional, parameterized multiscale systems to enable rapid parameter studies, sensitivity analyses or uncertainty quantification.
The work focuses on the adaptive modeling of degradation processes that lead to a change in the underlying geometric structure of the porous electrode material. In particular, the local deposition of metallic lithium (lithium plating) is investigated in this project.
