  • Battery cases typically require a conductive pin which feeds into the case through a dielectric material which insulates the pin from the conductive case wall. It is generally critical that the feedthrough be hermetically sealed. Techniques are known for forming a hermetic seal between a metal pin of high melt point material and a ceramic cylinder surrounding the pin. Moreover, an annular metal collar of high melt point material can be hermetically sealed around the ceramic cylinder.
  • the present invention is directed to an improved case/feedthrough construction enabling the use of a low melt point case material, e.g., aluminum, in conjunction with a ceramic-metal feedthrough subassembly which requires the application of a high temperature to form a hermetic seal.
  • a low melt point case material e.g., aluminum
  • a case cover comprised of a layer of high melt point material and a layer of low melt point material is used to respectively seal to a high melt point collar on the feedthrough subassembly and a low melt point case.

  • a hermetic seal can be formed between the ceramic and metal by proper application of processes and materials.
  • Ceramic to stainless and ceramic to titanium are particular examples of materials that can be bonded to form hermetic seals.
  • Braze bonding for example, aluminum oxide and zirconium oxide ceramic to metals, including titanium, stainless steel, molybdenum, tantalum, and cobalt-chromium alloys, can be done using a braze, comprising 30% nickel and 70% titanium (U.S.
  • braze bond includes the preferred method for joining zirconium oxide containing 3% yttrium to preferably a metal alloy, namely titanium and niobium (55% Ti and 45% Nb), using the nickel-titanium braze (50% Ni and 50% Ti) (U.S. Provisional Patent Application,
  • a pin 1 of stainless steel or titanium or one of the other aforementioned metals and a ceramic core 2 of aluminum oxide or zirconium oxide the pin 1 and core 2 can be hermetically bonded utilizing a high temperature brazing or baking process.
