Sustainable and high-performance solid-state electrolytes address a clear need in battery R&D. The FUNCY-SSB project will develop sustainable by design solid-state electrolytes with enhanced electrochemical performance.

A synergistic combination of sulfide electrolytes and polymers as functional surface coatings will be used to fabricate solid-state electrolytes. Semantic technologies for digitalising synthesis and manufacturing processes will improve interoperability and speed up the development. Recycling studies and economic/ecological potential analyses will address recyclability and sustainability of the SSEs. A pouch cell prototype will demonstrate the functionality of the FUNCY-SSB electrolyte. The advancements will enable solid-state Li-ion batteries for transportation and the project results will impact the availability of components for future batteries.
