Fraunhofer researchers report significant extension to Li-S cycle life with silicon anodes and CNT-sulfur composite cathodes

Green Car Congress

Lithium-sulfur batteries are of great interest for electromobility applications, among others, due to their high specific energy and relatively low cost, but are challenged by significant capacity decay over cycling. Li 2 S) can be accommodated more easily, leading to better cycle stabilities. Honolulu PRiME 2012.
