    摘要： Advanced implanted medical devices require long-lived, reliable power supplies. Lithium-ion batteries can be used to meet this need if they can be assured of maintaining a hermetic seal while implanted. The invention is a hermetic seal for a lithium-ion battery where the battery heater (5) is made of aluminum and the pin (1) is a conventional metal, such as platinum. The glass -to-metal seal utilizes low-temperature processable ALSG-32 glass, which has been demonstrated to bond to aluminum at temperatures below the melting point of aluminum and which has been demonstrated to exhibit excellent resistance to lithium battery electrolyte (9). ALSG­32 is a high phosphate glass having about 6.0% B2O3, 40.0% P2O5, 15.0% Na2O, 18.0% K2O, 9.0% PbO, and 12.0% Al2O3, expressed in mole percent.

    摘要： The invention is a hermetic seal that is compatible with lithium-ion electrolyte in lithium batteries. Pin feed throughs are sealed by compression, chemical bonding, and mechanical bonding between the metal pin (1) and a sealing glass (7), such as Cabal-12. The pin (1) may be coated with a metal or a metal oxide to enhance compatibility with the lithium battery environment. The pin (1) surface is roughened or mechanically shaped to ensure mechanical bonding with the glass seal (7). Mechanical bonds are also achieved by placing the pin/glass seal interface in compression by an external compression band.
