  • Patent number: 5725967
    Abstract: A container for a battery and a method for manufacturing such a container are provided. The container includes a housing; a cover adapted for attachment to the housing by crimping; and a gasket crimped to the cover and housing. One or more grooves are formed in the housing or cover or both. During assembly, the gasket is positioned between the cover and the housing, and a portion of the cover and a portion of the housing are crimped together causing the gasket to flow into and conform to the shape of the grooves. Placement of the gasket within the grooves increases the surface area of the resultant seal thereby improving the seal quality without significantly increasing the thickness of the battery or cell. In addition the grooves prevent the gasket from flowing out of the crimped seam and help to maintain the crimp pressure throughout the lifetime of the battery.

  • Patent number: 5702842
    Abstract: A process for charging and discharging zinc/bromine batteries with a plurality of anode and cathode chambers into and from which anolyte or catholyte fluids are fed and drained. Metallic zinc is deposited on the anode and atomic and/or molecular bromine is deposited at the cathode, and bromine is bonded in an only slightly water soluble complex with a complex-forming agent from the aqueous phase. The anolyte and/or catholyte fluids are circulated periodically. The oleophilic cathode phase is separated from the hydrophilic cathode phase. Only the aqueous phase of the catholyte is circulated through the cathode chambers, and the times at which the fluid is circulated is dependent upon the temperature of the anolyte in the anode chambers.
