LiBEST – Lithium-Ion Battery with High Electrochemical Performance and Safety Technologies

Sponsor: BMBF

Contact persons : Jannes Müller

Summary of the overall project:

The research project “LiBEST – Lithium-Ion Battery with High Electrochemical Performance and Safety Technologies” is funded by the German Federal Ministry of Education and Research (BMBF) and the Taiwanese Ministry for Science and Technology (MOST) as part of the program “New materials for battery systems – Funding of German-Taiwanese research cooperations (Battery DE-TWN)”.
The main research focus of the project is to increase the energy density of lithium-ion batteries through the targeted design of active material surfaces and the optimization of the electrolyte formulation for future high-energy battery concepts. Thus, the project addresses different anode (Si/C composites, Li-metal anode) and cathode concepts (Li-sulphur, layered oxides). Special attention is paid to the surfaces between active materials and electrolyte. These are specifically adapted to the requirements of cell chemistry to increase the energy density by means of functional coatings or newly developed additives as well as structuring of the active material. Another focus of the project is the development of additives to increase the safety of high-energy battery concepts.
