The Chair of Inorganic Non-metallic Materials (ANW) at the TU Dresden deals with the development and characterization of ceramic materials for high-performance applications. Particularly, active materials and electrodes for lithium-ion batteries are in the focus of research. The model-based optimization of the electrode design (e.g. layer thickness, porosity and particle size) is applied within the OptiEx project to support the performance optimization of high-energy electrodes. The computations are carried out with a focus on application orientation in order to provide direct input for the electrode processing of the project partners Fraunhofer IKTS and MEET. The processed electrodes are electrochemically characterized to validate the model predictions and provide kinetic parameters.
