Abstract
A miniature electrochemical cell of a primary or secondary chemistry having a total volume that is less than 0.5 cc is described. The cell casing comprises an annular sidewall connected to a base plate opposite a lid. A sealing glass forms a hermetic glass-to-ceramic seal with a dielectric material contacting a lower portion of the annular sidewall and a glass-to-metal seal with the base plate. A current collector supporting an electrode active material is connected to an inner surface of the lid using a parallel gap welding process. The lid is then welded to an upper edge of the annular sidewall to close the casing. A second, opposite polarity active material is electrically connected to the base plate. The lid also has a sealed electrolyte fill port that is axially aligned with an annulus residing between the inner surface of the annular sidewall and the first and second active materials.
