    • A sodium-sulfur battery is disclosed in one embodiment of the invention as including an anode containing sodium and a cathode comprising elemental sulfur. The cathode may include at least one solvent selected to at least partially dissolve the elemental sulfur and Na2Sx. A substantially non-porous sodium-ion-conductive membrane is provided between the anode and the cathode to keep sulfur or other reactive species from migrating therebetween. In certain embodiments, the sodium-sulfur battery may include a separator between the anode and the non-porous sodium-ion-conductive membrane. This separator may prevent the sodium in the anode from reacting with the non-porous sodium-ion-conductive membrane. In certain embodiments, the separator is a porous separator infiltrated with a sodium-ion-conductive electrolyte.

    • A rechargeable galvanic cell that has a negative electrode material made of a molten alkali metal (such as sodium or lithium). The galvanic cell also includes a positive electrode active material that may be sulfur or iodine. The positive electrode active material may be used in conjunction with a polar solvent. An ion-conductive separator is disposed between the polar solvent and the negative electrode material. The positive electrode active material has a specific gravity that is greater than the specific gravity of the polar solvent. Thus, the positive electrode active material is proximate the bottom of the positive electrode compartment while the polar solvent is above the positive electrode active material. The cell is designed to be operated at temperatures above the melting point of the alkali metal, but at temperatures that are lower than about 250° C.
