ABSTRACT:
A glass-to-metal seal for an electrochemical cell terminal includes a formed apertured plate and a tack-shaped terminal pin. The formed apertured plate has a relief ring of concavo-convex configuration and the terminal pin has the vertical section thereof within the aperture and the horizontal section spaced away from the plate. A glass seal is formed between the relief ring and about the terminal pin, including the space between the horizontal section and the plate by the application of heat and pressure within a carbon mold.
