    摘要: A high energy density electrochemical cell comprises an anode consisting essentially between about 63% and 92% lithium, on an atomic basis, and the balance essentially aluminum, a cathode and a nonaqueous electrolyte. Advantageously, the cathode is an electrochemically active transition metal chalcogenide, such as titanium disulfide, and the nonaqueous electrolyte is an organic solvent, such as dioxolane, having at least one lithium salt, preferably lithium perchlorate, dissolved therein.

    摘要: An alkaline battery having a divalent silver oxide (AgO) positive active material (cathode) in which gold ions are incorporated into the alkaline electrolyte on the positive side of the battery separator or barrier or added to the positive active material. The gold additive improves the stability of the divalent silver oxide (AgO) active material in the aqueous alkaline electrolyte without adversely affecting the electrochemical reactions during the discharge of the battery. The additive is present in the battery in amounts ranging from about 0.1 to about 10% by weight of silver in the divalent silver oxide positive active material. It is preferred that the divalent silver oxide active material contain at least 50% by weight of divalent silver oxide (AgO) with the balance of the active material comprising monovalent silver oxide (Ag2O) and metallic silver. The gold additive may be combined with other additives and has been found to be particularly effective in some batteries when combined with mercury and incorporated into either the positive active material or the electrolyte on the positive side of the separator.

    摘要: The capacity of an electrical energy storage device containing a high surface area carbon cathode, a metallic anode, and a fused salt electrolyte in contact with the electrodes, can be greatly enhanced by the addition of a tellurium compound directly to the electrolyte or to the carbon cathode. On passage of an electric current through the system, the tellurium becomes permanently bonded to the carbon of the cathode thereby forming an ''''active'''' tellurium species that manifests itself as a characteristic plateau in the discharge profile of the cell.

    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: Method for producing a battery electrode, particularly a zinc electrode, of improved strength and stability, and which has a porous cellular structure, by mixing an aqueous dispersion of electrode material such as zinc oxide, with an aqueous dispersion of a latex type polymer such as a fluorocarbon polymer, e.g., polytetrafluoroethylene, casting a film of such mixture, drying the film, sintering the dried film, and rolling such sintered film, to form a fibrous polymer structure binding the particles of electrode material. The resulting sintered and rolled film can be employed per se as an electrode, e.g., a zinc electrode, or such film can be ground and the ground particles then compacted to form an electrode.
