Role in the project: DLR will be involved in production, characterization, and experimental validation of firstly flexible cathodes for Li-S batteries and secondly suitable anodes for a flexible battery setup consisting of lithium, magnesium or silicon.

Relevant expertise: The DLR-Institute of Engineering Thermodynamics (1), situated in Stuttgart, is active in the field of efficient energy storage systems that conserve natural resources, and next generation energy conversion technologies with a staff of 180 scientific and technical employees, engineers and doctoral candidates.. The department of Electrochemical Energy Technology (ECE) (2) has long-term experience in production and characterization of fuel cells and batteries (Li-S, Magnesium-sulphur, Lithium-ion, silicon-based, Li-air and Zn-air batteries). ECE provides extensive experience in the characterization of components of electrochemical energy converters with electrochemical and physical methods as well as in the diagnostics of batteries and determination of degradation effects. In addition, various production technologies for electrodes and gas diffusion electrodes as well as sulphur and polysulfide impregnation techniques into nanocarbon and smart textiles are available.

Added value: DLR is able to offer years of experience in battery field and committed to the optimization and understanding of next-generation batteries, including Li-sulphur, Li-air and Zn-air with various electrolytes, electrode designs and prototypes. The activities are carried out in an interdisciplinary team and take place in close cooperation with the department’s computational electrochemistry, located at Helmholtz-Institute Ulm (HIU). At the Computational Electrochemistry, multi-scale and multi-physics models as well as modern numerical simulation methods are developed and applied.
