Abstract

Abstract A sealed primary sodium-halogen cell is disclosed which comprises a casing, an anode positioned in the casing, the anode selected from the class consisting of sodium, sodium as an amalgam, and sodium in a nonaqueous electrolyte, a solid sodium ion-conductive electrolyte positioned in the casing adjacent the anode, and a cathode positioned adjacent the opposite side of the electrolyte, the cathode comprising sulfuryl chloride, sulfuryl chloride with aluminum chloride, or sulfuryl chloride with ferric chloride.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 83 words
A SEALED PRIMARY SODIUM-HALOGEN CELL COMPRISING A CAS ING, AN ANODE POSITIONED IN THE CASING, THE ANODE SELECTED FROM THE CLASS CONSISTING OF SODIUM, SODIUM AS AN AMALGAM, AND SODIUM IN A NONAQUEOUS ELECTROLYTE, A SOLID SODIUM BETAALUMINA ION-CONDUCTIVE ELECTROLYTE POSITIONED IN THE CASING ADJACENT THE ANODE, AND A CATHODE POSITIONED ADJACENT THE OPPOSITE SIDE OF THE ELECTROLYTE, THE CATHODE ONLY COMPRISING A LIQUID SELECTED FROM THE CLASS CONSISTING OF SULFURYL CLORIDE SULFURY CHLORIDE WITH ALUMINUM CHLORIDE AND SULFURYL CHLORIDE WITH FERRIC CHLORIDE.
Claim 2
Dependent Claim 83 words
A SEALED PRIMARY SODIUM-HALOGEN CELL COMPRISING A CAS ING, AN ANODE POSITIONED IN THE CASING, THE ANODE SELECTED FROM THE CLASS CONSISTING OF SODIUM, SODIUM AS AN AMALGAM, AND SODIUM IN A NONAQUEOUS ELECTROLYTE, A SOLID SODIUM BETAALUMINA ION-CONDUCTIVE ELECTROLYTE POSITIONED IN THE CASING ADJACENT THE ANODE, AND A CATHODE POSITIONED ADJACENT THE OPPOSITE SIDE OF THE ELECTROLYTE, THE CATHODE ONLY COMPRISING A LIQUID SELECTED FROM THE CLASS CONSISTING OF SULFURYL CLORIDE SULFURY CHLORIDE WITH ALUMINUM CHLORIDE AND SULFURYL CHLORIDE WITH FERRIC CHLORIDE.
Claim 3
Dependent Claim 82 words
A sealed primary sodium-halogen cell comprising a casing, an anode positioned in the casing, the anode selected from the class consisting of sodium, sodium as an amalgam, and sodium in a nonaqueous electrolyte, a solid sodium beta-alumina ion-conductive electrolyte positioned in the casing adjacent the anode, and a cathode positioned adjacent the opposite side of the electrolyte, the cathode only comprising a liquid selected from the class consisting of sulfuryl chloride, sulfuryl chloride with aluminum chloride, and sulfuryl chloride with ferric chloride.
Claim 4
Dependent Claim 82 words
