Master's student (m/f/d) Design and implementation of substitute tests to depict the damage behavior of lithium-ion cells during thermal runaway

Dr. Ing. h.c. F. Porsche AG • Weissach • 1d ago

Tasks

The objective of this work is to design and implement a surrogate test to investigate the damage behavior of lithium-ion cells during thermal runaway. Based on previously conducted cell tests, the mechanical and thermal stresses caused by the cells will be analytically determined. A test setup will then be developed that realistically simulates the stresses caused by gas and particle release from the cell and is variably adjustable. After commissioning, the test setup will be validated using various material tests and compared with results from cell tests.

These tasks include, in particular:

Research into thermal runaway of lithium-ion cells Analysis of the damage mechanisms of materials during thermal runaway Design and constructive implementation of a surrogate test setup to model the damage behavior of thermal runaway Commissioning and conducting tests with different material samples Optimization and evaluation of the damage behavior of the test bench under different boundary conditions Comparison with other surrogate tests and single-cell tests For more detail, salary and company information, use the apply link
