The Fraunhofer Institute will hold its third annual workshop on lithium-sulfur batteries in Dresden, Germany, on November 12 and 13. Lithium-sulfur is a leading contender for the battery chemistry of the future, and Fraunhofer believes that novel materials such as nanostructured carbon/sulfur composite cathodes, solid electrolytes and alloy-based anodes will significantly enhance performance.
Dr Oliver Gröger from Volkswagen will give a talk on recent developments in Li-sulfur batteries with silicon anodes, with a comparison to commercially available NMC-based batteries. Dr Gröger is one of the inventors of a new metal-sulfur battery system that features a multi-layered separator to reduce polysulfide shuttling and dendrite growth from the metal anode.
There will also be presentations on such topics as: cathode design and processing; solid electrolyte membranes and thin films as polysulfide shuttle barriers for Li-S cells; stabilization of sulfur and lithium sulfide cathodes by tuning particle architecture and electrolyte composition; and structure and morphology of carbon black and graphite.
Participants can also sign up for an optional tour of the Fraunhofer labs.
