Effect of cell ageing on the thermal energy released and battery gas composition during abuse tests
The effect of the cyclic ageing process on the safety behavior of lithium-ion batteries (LIB) was investigated using 21700 cells. An in-house developed 2-phase calorimeter was used to investigate the energy released by the cells during abuse tests. The method makes it possible to distinguish between the energy released by gases/particles and the heat in the cell residue. The influence of the ageing mechanism was also investigated. The results have a direct influence on possible cell proliferation. These investigations were supplemented by determining the volume of gas released and its composition.
Curriculum vitae
After studying technical chemistry at the University of Oldenburg and completing his doctorate at the UFZ - Environmental Research Center Leipzig-Halle, Michael received his doctorate from the University of Leipzig, Department of Analytical Chemistry. As a post-doctoral researcher, he was project manager for national and international water projects at the Department of Water Chemistry at the University of Karlsruhe.
After several years as a laboratory manager in a privately run analytical laboratory for water analysis and as a manufacturer of a specialized LC-OCD chromatographic system, he moved to the Applied Electrochemistry department at Fraunhofer ICT in 2012 to set up gas analysis for the battery test facility there. His main areas of work are the development and application of analysis techniques and sensors for battery gas and water analysis.
