Fraunhofer IWS Advances Solid-State Li-S Battery Cells
Fraunhofer IWS is researching solid-state Li-S battery chemistry, aiming to deliver high-energy cells with improved cycle life and safety.
The research, supported by the German Federal Ministry of Research, Technology and Space and the EU's Horizon Europe programme, is focused on two projects: AnSiLiS and TALISSMAN.
- Overcoming limitations of conventional Li-S batteries, which suffer from poor cycle life due to liquid electrolytes promoting soluble polysulfide formation.
- Pursuing a solid-state approach, converting sulphur directly into lithium sulphide without liquid electrolyte.
Early lab results suggest specific energy above 600Wh/kg with stable cycling.
