Pressure seal for lithium battery, manufacturing method and use in a lithium battery, and lithium battery implementing such a seal

摘要

The glass-metal penetration for the electrical insulation between two poles of a lithium battery, comprises a glass (1), which has good resistance in organic electrolyte medium combined with a lithium salt and a thermal expansion coefficient of lower than 7x 10 - 6/[deg] C, a metal pin (2), and a body (3). Independent claims are included for: (1) a method of fabricating a glass-metal penetration; and (2) a lithium battery equipped with a glass-metal penetration.
