摘要:
An electrochemical storage cell or battery with one anode chamber containing molten alkali metal as the anolyte and one cathode chamber containing sulfur-containing catholyte substance, the anolyte and catholyte separated by an alkali-ion-conducting solid electrolyte. The cathode chamber is bounded by a cellwall having a protective layer of a light weight metal also serving as a current collector. The light weight metal in the regions in contact with the catholyte is coated with a metallic alloy which under conditions of operation has certain properties of adhesion, conduction, resistance, corrosion and solubility.

Electrochemical storage cell with an anode chamber and a cathode chamber separated by a solid electrolyte. At least one of the chamber adjacent to the solid electrolyte and a supply chamber shield from both the solid electrolyte and the reaction chamber. At least one connected between the reaction chamber and the supply chamber for flow of reactants, and temperature controlled shut-off means for closing off the connection when a predetermined temperature above the operating temperature of the cell is reached.
摘要:
An electrochemical storage cell or battery based on an alkali metal and sulfur having at least one anode chamber and at least one cathode chamber separated from each other by an ion-conducting solid electrolyte, and felt with course-pores and/or low electric conductivity and felt with fine-pores and/or higher electric conductivity located in the cathode chamber, with the felt of coarse-pores and/or low conductivity disposed near the solid electrolyte and the felt of fine-pores and/or higher conductivity disposed further away from the solid electrolyte. This permits rapid and more complete recharging of the cell for covering peak loads in electrical networks.
摘要:
Electrochemical storage cell of the alkali metal and chalcogen type with an anode and a cathode chamber separated by a solid electrolyte wall and confined by a metal wall. A first current collector has an outer sub-part which extends outside the reactant chamber enclosed by the solid electrolyte, and an inner sub-part which extends into the interior of this reactant chamber. The outer sub-part and the inner sub-part are connected to an electrically conducting contact element which melts at a predetermined temperature exceeding the operating temperature of the cell. A second current collector is formed by part of the metal wall which confines the other reactant chamber.
摘要:
An electrochemical storage cell or battery with at least one anode filled with a molten alkali metal as the anolyte and at least one cathode chamber filled with a sulfur-containing catholyte substance with the anode chamber and the cathode chamber separated from each other by an alkali-ion-conducting solid electrolyte. To the catholyte substance is added an additive which converts the sulfur chains into an electrically charged state for obtaining electromigration of the sulfur phase. This induces mobilization of the sulfur phase in the cathode chamber and prevents major accumulation of liquid sulfur as an insulator. As a result the cell can be repeatedly recharged with large currents to a greater capacity. Additives are a dienophilic compound or a reaction product of a dienophilic compound and sulfur.
摘要:
An electrochemical storage cell or battery based on an alkali metal and sulfur having at least one anode chamber and at least one cathode chamber separated from each other by an ion-conducting solid electrolyte, a felt fabric with capillary activity located in the cathode chamber, and an additive lowering the viscosity of the sulfur in the cathode chamber. Preferred additives are selenium, boron and iodine. Lowering the viscosity of the sulfur permits recharging the cell to a greater capacity.
摘要:
Electrochemical storage cell or battery based on sodium and sulfur having an anode chamber and a cathode chamber separated from each other by a dividing wall capable of conducting sodium ions, is provided with a screening electrode disposed in the chamber containing sulfur as a reactant between the dividing wall and the outer cell wall of said chamber to electrically screen the cell wall and thereby minimize corrosion of the cell wall.

摘要:
A freeze-drying process which reduces loss of the freeze-dried product comprising adding a liquid solution comprising a solid product dissolved in a solvent to a glass container having its inside surface coated with a silicone material; subjecting the container with the liquid solution therein to acceptable operable freeze-drying conditions to remove the solvent and leave the solid product in the container in the form of a dense compact coherent solid; and sealing the container to maintain the solid product stable over a useful storage shelf life.An article of manufacture comprising a sealed glass container having its inside surface coated with a silicone material and containing an in situ freeze-dried dense compact coherent solid product.
摘要:
A transdermal delivery system (TDS) having: a carrier layer (cover layer) impermeable to the substances/active ingredients to be delivered, a membrane permeable to the substances/active ingredients to be delivered, a reservoir containing substances/active ingredients to be delivered, the reservoir being provided between the carrier layer and the membrane; and a removable film, wherein the carrier layer and the membrane comprise electrodes such that the electrode(s) of the membrane serve(s) as counterelectrode(s) to the electrode (the electrodes) of the carrier layer, is disclosed.
