The starting point for cost-effective energy storage offering a high energy density as well as improved performance, lifetime, and efficiency lies within the underlying active materials. The aim of component development is to transfer the potentials of new materials onto the level of components. Deciding influencing factors are hereby, in addition to the electrical conductivity, the specific surface, the porosity, the particle sizes and morphologies, and in particular the (electro) chemical stability as well as the scalability of production. A further important aspect is also the fundamental electrode design, which must always be adapted to the respective materials. The applied material development used thus represents the link between the basic research and the battery cell.

We work on material and component development for modern energy storage technologies under the following topics:
