Abstract: An electrochemical cell has a cylindrically-shaped casing tube with at least first and second lithium sheets swaged onto its inner surface. The first lithium sheet has respective spaced apart first right and left edges, and the second lithium sheet has spaced apart second right and left edges. The first and second right edges and the first and second left edges of the swaged first and second lithium sheets are adjacent to but spaced apart from each other by about 0.5° to about 1° about the inner circumference of the cylindrically-shaped casing tube. A novel process for swaging the first and second lithium sheets onto the inner surface of the casing tube is also described.

Abstract: A miniature electrochemical cell of a primary or secondary chemistry with a total volume that is less than 0.5 cc is described. The cell has a casing comprising an annular sidewall supported on a lower plate opposite an upper lid. The lid has a sealed electrolyte fill port. At least one electrolyte channel in the inner surface of the lid extends radially from the fill port and outwardly beyond an outer peripheral edge of the current collector. A current collector contacts an inner surface of the lid with a first electrode active material contacting the current collector. An opposite polarity active material contacts the lower plate. A dielectric material coats the lower open end of the annular sidewall and a portion of the inner surface of the sidewall. A glass seals the dielectric material to the lower plate. An electrolyte activates the electrode assembly.
