Abstract

The present invention provides an alkali- and/or alkaline earth-ion - sulfur battery comprising at least one cathode containing: - a cathode current collector foil; - optionally a conductive adhesive interlayer; - a primary cathode mass layer, containing a conductive dimensionally stable porous host structure, sulfur as an active material, whereas preferably at least 20 % of the sulfur present is monoclinic sulfur allotrope, and optionally conductive additives, binders and pore-forming additives; - a secondary cathode mass layer, containing sulfur and alkali-ion- and/or alkaline earth-ion-intercalating material; - optionally a layer, containing graphene oxide and/or reduced graphene oxide, heteroatom Group VIIa and/or Group Va elements co-doped graphene, and a Group VIIa and/or Group Va heteroatom-containing polymer; and/or at least one anode containing - an anode current collector foil; - optionally a conductive adhesive interlayer; - a primary anode mass layer, containing a conductive dimensionally stable porous host structure, a metal capable of forming intermetallic alloys with an alkali metal and/or an alkaline earth metal, and optionally conductive additives, binders and pore-forming additives; - optionally a secondary anode mass layer, containing graphene oxide and/or reduced graphene oxide, heteroatom Group VIa elements co-doped graphene, and a polymer, preferably an elastomeric polymer; - an alkali metal and/or an alkaline earth metal, preferably in the form of foil or powder. and at least one separator. The resulting cells offer a wide range of economic and ecological advantages over the currently available cells, as well as allowing versatility of materials and production processes.
