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 closure system for the electrolyte fill port of an electrochemical cell is described. A cell header has an electrolyte fill port comprising an upper opening sidewall extending from a header upper surface to an intermediate ledge located part-way through the header thickness. The ledge extends from a lower edge of the upper opening sidewall to an upper edge of a lower opening sidewall, the lower opening sidewall extending to the header lower surface. With respect to an axis of the electrolyte fill port, the upper opening sidewall has a first radius r1 and the lower opening sidewall has a second radius r2 at the ledge, the lower opening sidewall extending downwardly and inwardly along the axis from the second radius r2 to a third radius r3 at the header lower surface. The second radius r2 at the ledge is greater than the third radius r3 at the header lower surface. A closure system for an electrolyte fill port comprises a lower closure member secured to the lower opening sidewall by a lower weld; and an upper closure member secured to the upper opening sidewall by an upper weld. Importantly, the lower opening sidewall is provided with rifling.
