摘要： An improved secondary battery or cell of the type having: (A) one or more anodic reaction zones containing a molten alkali metal reactant-anode in electrical contact with an external circuit; (B) one or more cathodic reaction zones containing (1) a cathodic reactant which, when said battery or cell is at least partially discharged, is selected from the group consisting of (i) a single phase composition comprising molten polysulfide salts of said anodic reactant and (ii) a two phase composition comprising molten sulfur and molten sulfur saturated polysulfide salts of said anodic reactant; (C) a cation-permeable barrier to mass liquid transfer interposed between and in contact with said anodic and cathodic reaction zones; and (D) electrode means within said cathodic reaction zone for transporting electrons to the vicinity of said cation-permeable barrier during discharge of said battery or cell and for transporting electrons away from the vicinity of said cation-permeable barrier during charge of said battery or cell, said electrode means being in electrical contact with both said cation-permeable barrier and said external circuit and being immersed, at least in part, in said cathodic reactant. The improvement of the invention comprises an electrode means which comprises first and second electrodes, the first electrode being (i) adapted to be used in charging the battery or cell, (ii) disposed in a first region of the cathodic reaction zone, (iii) contiguous with or adjacent to a first section of the cation-permeable barrier and (iv) formed of a conductive material which is more readily wet by molten polysulfide than by molten sulfur, and the second electrode being (i) adapted to be used in discharging the battery or cell, (ii) disposed in a second region of the cathodic reaction zone, (iii) contiguous with or adjacent to a second portion of the cation-permeable barrier and (iv) formed of a material which is more readily wettable by molten sulfur than by molten polysulfide.

摘要： A REDUCED OPERATING TEMPERATURE FOR A SODIUM-SULFUR BATTERY IS ACHIEVED WITH A NEW ELECTROLYTE COMPRISING SODIUM POLYSULFIDE, ALUMINUM SULFIDE OR ALUMINUM POLYSULFIDES AND FREE SULFUR WHEN THE ELECTRODES ARE IN THE CHARGE CONDITION. THE ELECTROLYTE, WHICH HAS A MELTING POINT IN THE RANGE OF APPROXIMATELY 200*C., PERMITS THE BATTERY TO BE SEALED WITH POLUTETRAFLUOROETHYLENE SEALING MATERIALS. BASED ON PRESENT LIMITED DATA, IT APPEARS THAT THE REDUCED MELTING POINT TEMPERATURE OF THE ELECTROLYTE CAN BE OBTAINED WITH SOLUTIONS IN WHICH THE RATIO OF THE MOLE PERCENT OF SODIUM POLYSULFIDE TO THE MOLE PERCENT OF ALUMINUM SULFIDE OR ALUMINUM POLYSULFIDE VARIES CONSIDERABLY.

摘要： Disclosed is a carbon felt impregnated with inorganic particles. The impregnated carbon felt can be used together with sulfur in a cathode of a sodium-sulfur (Na—S) battery. Also disclosed is a method for producing the impregnated carbon felt. According to exemplary embodiments, the problem of the prior art can be solved in which inorganic particles such as alumina particles are not directly adhered to carbon felts, thus necessitating complicated processes. In addition, a slurry including an inorganic binder and alumina particles can be used to directly coat the alumina particles on the surface of a carbon felt, making the production procedure very simple. Furthermore, the use of the carbon felt surface coated with the alumina particles in a Na—S battery increases the wicking of sodium polysulfides, suppresses the accumulation of sulfur as an insulator on the surface of beta-alumina as an electrolyte, and inhibits non-uniform aggregation of sulfur or sodium polysulfides on the carbon felt, so that the concentration polarization of charges can be reduced without a significant increase in the internal resistance of the battery, achieving high utilization efficiency of sulfur as a reactant.

摘要： Sulfur containing nanoparticles that may be used within cathode electrodes within lithium ion batteries include in a first instance porous carbon shape materials (i.e., either nanoparticle shapes or “bulk” shapes that are subsequently ground to nanoparticle shapes) that are infused with a sulfur material. A synthetic route to these carbon and sulfur containing nanoparticles may use a template nanoparticle to form a hollow carbon shape shell, and subsequent dissolution of the template nanoparticle prior to infusion of the hollow carbon shape shell with a sulfur material. Sulfur infusion into other porous carbon shapes that are not hollow is also contemplated. A second type of sulfur containing nanoparticle includes a metal oxide material core upon which is located a shell layer that includes a vulcanized polymultiene polymer material and ion conducting polymer material. The foregoing sulfur containing nanoparticle materials provide the electrodes and lithium ion batteries with enhanced performance.

摘要： Two or more module batteries are arranged in an array and connected through wiring. The outer surface of a first side wall of a case faces in a first direction without facing the others of the two or more module batteries. Second and third side walls of the case are spaced from each other in a second direction. The first direction and the second direction are perpendicular to each other. Two or more string groups are arranged linearly in the second direction. The positive electrode current collecting part extends along the inner surface of the second side wall, the positive electrode extension part extends along the inner surface of the first side wall, and the positive electrode feedthrough part penetrates through the first side wall. The positive electrode current collecting part, the positive electrode extension part, the positive electrode feedthrough part, and the wiring are electrically connected to one another.
