Abstract
A header device for use with an electrochemical cell requiring a hermetic seal between the header, the terminal pin, and the body of the cell. A stainless steel header is sized to fit the cell body and hermetically sealed to the body. An annular glass ring is bonded to the header. Centered in and bonded to the ring is a terminal pin consisting of a solid central core of material selected from nickel and nickel alloys and a stainless steel sleeve surrounding the core. The thickness of the sleeve is less than 0.01 inches. The annular glass ring electrically insulates the stainless steel header from the terminal pin. The sleeve is bonded to the core by a nickel braze. The bonding of the pin to the ring and the ring to the header is accomplished at an elevated temperature of at least 1800 degrees Fahrenheit.
