NOVEL GLASS TO METAL SEAL

It has been discovered that the connection between a current collector and a molybdenum terminal pin can be improved by roughening the terminal pin. However, a roughened terminal pin detracts from the integrity of the glass-to-metal seal. To overcome this, a sleeve or couple surrounds that portion of the roughened terminal pin that will be sealed to the insulating glass. The sleeve or couple is welded at each end to the terminal pin, and a glass-to-metal seal is formed between the sleeved terminal pin, the insulating glass, and the metallic lid. The resulting assembly contains a portion of the terminal pin that has a roughened surface and is suitable for making a high strength connection to a current collector of a primary or secondary lithium ion battery, and to a sleeved portion which has a relatively smooth surface that provides a high strength for a glass-to-metal seal.
