Derivation of the mechanical behavior of battery components from the microstructure

Derivation of the mechanical behavior of battery components from the microstructure

Background:
The newly founded Battery4Life competence center is investigating the research field of battery safety and sustainability. To be able to assess the safety of electric vehicles in accident scenarios, their mechanical behavior is of great interest. This extends over several orders of magnitude, from the full vehicle to the individual battery cell to the microstructure of the individual materials. The prediction of how a defined microstructure will behave macroscopically is an important issue to be able to take the behavior of new, partially innovative battery concepts into account early in vehicle development.
This problem is being investigated by Battery4Life in collaboration with the Institute of Strength of Materials.

Your goal is to develop a method for estimating the macroscopic material behavior based on microstructure and to derive information essential for an adequate prediction.

Tasks:
• Get familiar with the structural design of lithium-ion batteries and their simulations
• Understand approaches for the homogenization of microstructures in the field of the finite
element method using LS-Dyna software
• Develop a model of a microstructure and use it to determine the macroscopic material behavior
• Determine the relevant parameters of this microstructure

Organizational:
• Start: at any time
• Language: German or English
• Supervision: Assoc.Prof. Manfred Ulz (Institute of Strength of Materials)
• € 3.000,- for successful completion of the Thesis
