Lithium Sulfur Seems to be a Stand Out
"Fraunhofer IWS in Dresden, Germany will hold its 3rd annual workshop on Lithium-sulfur batteries from 12-13 November 2014," reports Green Car Congress.
Any workshop/conference/research on lithium-sulfur interests us due to this statement by Fraunhofer:
"...Lithium-sulfur batteries are the most promising choice for future energy storage systems, with novel materials such as nanostructured carbon/sulfur composite cathodes, solid electrolytes and alloy-based anodes expected to enhance significantly the cell’s performance."
But what really caught our attention in regards to this workshop is that Volkswagen will be the sole OEM in attendance:
"The sole OEM presentation will be a talk by Dr. Oliver Gröger from Volkswagen AG on recent developments on Li-sulfur batteries with silicon anodes and a comparison to commercially available NMC-based batteries."
Green Car Congress adds:
"Volkswagen AG filed a patent application in October 2012 (published in December 2013) on a new metal-sulfur battery system (e.g., lithium-sulfur, although other metals from the group of lithium, sodium, magnesium, calcium, aluminum and zinc are supported), with a focus on a novel multi-layered separator to reduce polysulfide shuttling and dendrite growth from the metal anode; Dr. Gröger was one of the inventors."
So, is Volkswagen leading the lithium-sulfur charge? It sure seems that's the case.
