Abstract (englisch):

The thermal behaviour of lithium-ion cells and their active materials depend on a large variety of internal and environmental physicochemical parameters, which are still not deeply understood. Additionally, the specific materials design and the use of nanoscale materials influences heat generation and heat dissipation during operation of the electrochemical cells. Therefore thermal characterization of the cells, batteries and their individual active and passive materials is required in combination with multiscale electrical electrochemical, thermal and thermodynamic modelling to obtain quantitative and reliable thermal and thermodynamic data. Combined electrochemical-thermal characterization techniques will be presented, which are needed in order to study the influence of ageing phenomena on different modes of heat generation and to collect data that can be used in battery management systems.
