Predicting short circuit of Li-ion battery cells during mechanical abuse using Finite Element method


Li-ion batteries is today the dominating solution for energy storage in electric vehicles (EVs). A key aspect in the EV design is safety. For example, in the case of a car crash, mechanical deformation of the battery cells can lead to electrical short circuits that may end up in potential safety issues. It is therefore crucial to minimize the risk for such events in the EV design.

The physical cause for short circuiting is the occurrence of electron transfer between the cathode and anode materials inside the battery cell. Such event can be triggered by internal causations (e.g. lithium dendrite growths), or by external abusive scenarios, e.g. mechanical, electrical and thermal abusive cases. In this thesis, the main focus will be on mechanical abusive scenarios associate with EV application. Modelling strategies, using Finite Element (FE) analysis, for predicting short circuit in battery cells due to mechanical loading will be studied. The work will build up on state-of-the-art mechanical battery models and pre-studies on short circuit modelling available at Volvo Cars.


Scope of the Master Thesis:
•    Evaluate modelling strategies for predicting short circuit in battery cells due to mechanical abuse conditions available in the literature.
•    Study failure criteria for short circuiting linked to mechanical loading.
•    Set up FE-model(s), based on selected methodology, for combined mechanical and electrical analysis of single battery cells.
•    Analyze available material/cell data and study the influence of the model parameters.
•    (If available) compare numerical predictions with experimental data.



We are looking for motivated students pursuing a Master of Applied Mechanics or similar. A genuine interest and curiosity in the subject matter and excellent analytical and communication skills, both oral and written English, are needed. The ideal candidate has a background in analytical work, including structural simulations (FEM).


•    The duration of the Thesis is 20 weeks
•    The Thesis starts in Jan 2024
•    30 ECTS (academic credits) if in agreement with your Thesis Advisor in University 
•    This thesis is suitable for 1- 2 students
