SFB 458:  Ionic-Motion in Materials with Disordered Structures - From Elementary Steps to Macroscopic Transport -

Subject Area Chemistry
Physics
Term from 2000 to 2009
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5484095
 
In collaborative research centre 458, we address the central questions of a discipline now known as SOLID STATE IONICS. These concern the disordered structures and the detailed ionic transport mechanisms in ion-conducting materials. The latter become increasingly important for high-technology applications such as advanced battery systems, fuel cells and chemical sensors. The dynamics of mobile ions in materials with disordered structures are investigated on a wide range of time and length scales extending from the tracing of elementary steps to the measurement of macroscopic transport. Materials studied include crystals (with structural disorder in at least one sublattice), glasses, and polymers. Work on these materials comprises the synthesis and characterisation of new disordered ion-conducting substances, the experimental study of ionic motion and mass transport by complementary techniques (tracer diffusion, NMR, conductivity spectroscopy and others) and the attempt to understand the complex ion dynamics by the help of numerical simulations and physical models. This comprehensive programme will provide a basis for designing materials with optimised ion-transport properties.
