oriented aspects of this battery technology. We are active in the

development and optimization of new materials for both the positive and

the negative electrode. Electrochemical and in-situ X-ray diffraction

measurements are used to obtain fundamental thermodynamic, kinetic,

and structural data. These experiments, in combination with model

calculations, contribute to the improvement of the  battery materials. In

parallel, complete composite electrodes are prepared and characterized

electrochemically and with routine methods such as  porosimetry and

scanning electron microscopy. This combination of preparative and

characterization work has led to improvements in their cycle life and

specific charge and to increases in the achievable  maximum current

density. In this way comprehensive knowledge has been gathered about

small-scale electrodes

electrodes, which is now transferred to the

development of large-area, flexible electrodes. In addition, fundamental

studies on safety related aspects of this battery technology are

performed. Detailed investigations of the interaction of the electrodes

with the electrolyte solutions and the behaviour of the cells under

extreme conditions are accomplished by applying advanced analytical

methods such as in-situ FTIR and Raman spectroscopy, in-situ mass

spectrometry, and differential thermogravimetric analysis.

Interfaces & Capaciators: Surface analysis is essential for the

understanding and optimization of catalytic and electrochemical

interfaces and provides information about processes and electronic and

molecular properties on a microscopic scale. The main topics at present

are catalysis of nano particles and electrocatalysis,
