Expertise in battery chemistry, innovations in electrode production and modern cell manufacturing technologies are brought together on an interdisciplinary basis. This team develops new solutions from materials to manufacturing processes to prototype cells and their evaluation. The focus is on lithium-based high-energy cells, such as lithium-ion, lithium-sulfur and solid-state batteries. In this way, the ABTC addresses the holistic process chain for the development of new battery cells and transfers new research results from the laboratory into application-relevant prototypes.
November 11—12, Dresden. November 5—6, Dresden. Lithium-ion batteries LIB and thus electromobility have found their way into various mass markets. Research focuses on the further improvement of performance characteristics — especially energy density — and on cost-effective and environmentally friendly production processes.
Based on a fundamental understanding of materials and experience in battery cell design, multilayer pouch cells are being constructed and evaluated in an application-oriented manner. This innovative dry-coating process enables the production of battery electrodes without solvents and drying processes. The complex cell chemistry requires further development of cell components and their coordination with each other. The ABTC has developed and patented numerous concepts for this purpose.
Special electrolyte formulations are used to regulate the formation of polysulfides, and carbons form the conductive framework for the conversion of the sulfur. Using solid electrolytes, the solid Li-S battery is also being investigated as a particularly promising cell system.
Lithium metal anodes are manufactured, modified and automatically processed in cell assembly. The developments are demonstrated in prototype cells with up to 25 Ah capacity and tested with application-relevant protocols.
