摘要： 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.
