The development of efficient, high-performance and long-term stable Lithium ion batteries demands the use of innovative anode and cathode active materials. As an expert in synthesis and modification of precursor-derived ceramics, the focus of the group is on research and development of precursor-derived active materials via the specific and direct tuning of parameters such as material composition, structure and morphology, which play a key role in material properties.
Main topic in the research field of anode active materials are silicon-based, polymer-derived materials possessing high specific charge/discharge capacities. Research on cathode materials is focused on materials such as LiFePO4, LiMnPO4 und LiFexMn1-xPO4.
In cooperation with system and technology developers, synthesis and processing of electrode materials are optimized for industrial scaled processing routes.
