Thermal Runaway of li-ion batteries; studies of gases and heat release

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.
