Definitions

  • Glass seals are used in various arrangements including batteries and other electrochemical cells .
  • glass seals are used to seal the battery container while allowing one or more electrical terminals to extend through the seal for interior/exterior connection thereto .
  • the term "feedthrough" shall be used herein to describe such arrangements in generic fashion.
  • corrosion has been encountered.
  • batteries which include various organic electrolyte systems give rise to corrosion and cracking of glass and metal feedthrough components.
  • a special glass composition has developed by Sandia National Laboratories which exhibit improved corrosion resistance. It is generally referred to as CABAL-12 glass.
  • the ' general purpose of this invention is to provide a combination of metal and CABAL-12 GLASS for improved feedthrough structures in battery and electrochemical cell applications.
  • This invention relates to feedthrough structures which utilize CABAL-12 glass particularly for use in aggressive battery organic electrolyte environments e.g., a lithium thionyl chloride cell or cells of other active chemistries such as Mn0 2 , and CFX, for example. It has been discovered that this glass has a unique affinity for sealing to titanium and titanium alloys.
  • the invention relates specifically to hermetic, corrosion resistant, compression-type sealed feedthroughs utilizing single or multiple terminals or pins of niobium, tantalum, molybdenum and titanium or alloy thereof, contained within a header or sleeve of titanium or a titanium alloy, Titanium-6A1-4V being preferred.
  • FIG. 1 is a schematic cross-section of a battery header in accordance with the invention
  • Fig. 2 is a schematic cross-section of a feedthrough with sleeve according to the invention combined with a metal container for use as an electrochemical cell.
  • a header of typical construction is shown which includes a center pin or terminal 10, a glass seal member 12 and an outer member 14. This arrangement and that of Fig. 2 are typical feedthrough seal arrangements which may make use of the invention.
  • the invention in a preferred form includes a terminal 10 extending through a glass seal 12 which is received into a sleeve or header 14.
  • Sleeve 14 may be welded into an opening in a battery container 16 of, for example, stainless steel.
  • the assembly requiring forming weights, is placed in an oven or furnace and heated causing the glass to wet the metallic components forming a he_rmetic seal between the glass and the metal components.
  • Such a feedthrough may thereafter be welded if necessary, into any desirable container or the like.
  • terminal 10 consists essentially of niobium, or titanium or an alloy thereof.
  • Sleeve 14 is of titanium or a titanium alloy Ti-6A1-4V
  • the glass 12 is CABAL-12, which is of the following composition:
