Performance and safety are key features for batteries to fully penetrate the car industry. The demand for higher specific capacity and power for electric vehicles does, however, imply that more energy is available leading to an increased risk, should the worst happen. Thus a deeper understanding of critical failures in batteries is needed.
This project aims at realizing larger i-ion battery systems through a more profound understanding of the failure mechanisms causing thermal runaway. To this end, the flue gas formed and heat evolution during thermal runaway will be studied. Thereby, test methods contributing to the understanding of the flue gases and heat generation from burning li-ion batteries on both the macroscopic (industrial) and microscopic (prototype/lab) scale will be developed, aiming at bridging the gap in between the two types of experiments. This will lead to an understanding of the relevant chemical processes, which will serve as input parameters for computer simulations of battery behaviour. These will contribute to more effective battery testing and analysis.
