摘要

On the occasion of energy transition, new electrochemical storage systems based on new cell concepts will be needed to meet today's energy challenges like vehicle electrification or energy storage from renewable sources. Seen on long terms, battery cells have to be adjusted to their applications. Proven concepts are known to be nano structuring of active materials and hierarchical structuring of electrodes. Furthermore, new promising material classes with prospect on enhanced energy and power densities should be investigated concerning these aspects for future applications. In the context of this presentation, the methodology of our experimental based material design process within HiKoMat will be illuminated. The HiKoMat project is an interdisciplinary joint project with four key aspects -synthesis, imaging, measurement of electronic and ionic properties and modelling of the cell performance. HiKoMat, first tries to generate a detailed understanding of the process-structure-property relationships in hierarchically structured composite materials and based on this, second, the optimization of electrochemical performance for application. In work package 1 (WP1), the synthesis and characterization of hierarchically structured composites is pursued. In WP2 the synthesized structures as well as electrodes are characterized by means of multi-scale 3D imaging and the structures are modelled by methods of stochastic geometry. WP3 is concerned in determining electronic and ionic parameters like conductivities and diffusivity of individual particles and particle compounds, which are not accessible by standard solid-state methods up to now. At last, the numerical simulations in WP4 are needed to understand the effects from electrode architecture and they shall provide design criteria for the further development of hierarchically structured composite materials. This research project is supported by the Federal Ministry of Economics and Energy (BMWi), project No. 03ET6095A.
