Abstract
All-solid-state lithium-sulfur electrochemical cells and production methods thereof are described. The Li—S electrochemical cells comprise at least one multilayer component which comprises an ion-conductive solid electrolyte film, a positive electrode film containing a sulfur composite, and a negative electrode film containing lithium. Positive electrodes films, prefabricated electrolyte-positive electrode elements, their uses as well as methods of their production are also described.
