For the development of sulfide-based all-solid-state batteries, one of the key technological requirements is processing of the ceramic electrolyte powder into a thin, flexible and homogeneous film. In SUBLIME, different binders and binder combinations were tested to balance the mechanical and electrochemical performance of the electrolyte films using a wet chemical processing routine.
The obtained results are reported in SUBLIME’s latest open access publication Film processing of Li6PS5Cl electrolyte using different binders and their combinations.
This paper focuses on elucidating the relationship between the physicochemical properties of the binder materials and the resulting electrochemical and mechanical properties of the electrolyte films for all-solid-state battery component fabrication.
