摘要： A metal support disk for an electrochemical cell seal exerts a resilient outward radial force against the seal to maintain seal integrity over a wide range of operating temperature and, at the same time, exerts an upward force against the bottom of the metal end cap terminal of the cell to assure electrical contact between the anode inside the cell and the terminal. The disk includes a central, circular platform connected to an outer, sealing edge sealing flange by an annular flexure means which permits radially inward and outward movement of the sealing edge when the end of the cell is radially crimped during the sealing process. The crimping also moves the central portion of the disk up which results in the upward force being exerted against the end terminal. The flexure means is a sequential series of three annular, curved fibs with the first and third curved downward and the second curved upward. A ring depending radially outward and at an upward angie from the first fib connects the first fib to the second fib and helps to prevent plastic deformation of the disk during sealing.

摘要： An electrochemical cell having an on-cell tester for visually indicating the condition of the cell is provided with an electrically conductive metal ring pressed onto the negative terminal at the crimp seal end of the cell, to permit the tester lead to make an electrical contact with the negative terminal without shorting across the positive terminal of the cell. The ring has a cylindrical wall portion or gripping means which frictionally grips a corresponding mating cylindrical wall potion on the negative terminal and also has a flange portion adjacent the positive terminal. A layer of electrically insulating material disposed between the flange and positive terminal prevents electrical contact between the terminals. The tester lead is either permanently electrically connected to the ring or intermittently connected by the user, depending on the type of tester used.

摘要： A metal support disk useful in sealing an electrochemical cell exerts a resilient outward radial force against the seal to assure seal integrity over a wide temperature range and exerts an upward force against an adjacent metal end cap terminal to assure continued mechanical and electrical contact with the terminal. The support is a stepped disk having a centrally located, shallow, cylindrical pill-box, with the bottom of the pill-box extending radially outward into an annular ring. A spring means in the form of an S-shaped rim extends down from the periphery of the ring, terminating at its bottom in an outward extending flange. The edge of the flange presses a plastic seal member against the inside wall of the cell to form the seal.

摘要： An end cap assembly for an electrochemical cell, for example an alkaline cell, is disclosed comprising an exposed terminal end cap of single piece construction having a convoluted surface, an electrically insulating member and a metal support disk between the insulating member and the terminal end cap. The end cap assembly is inserted into the open end of the cell housing after the cell contents have been supplied. A portion of the end cap surface is a flat annular step which improves contact between the end cap and the electrically conductive portion of a condition tester for the cell which may be integrated into the cell label. The annular step is advantageously located at about right angle to the cell's longitudinal axis. The surface step is integral with the end cap and preferably located at about the same level as the shoulder of the cell housing at the end of the cell containing the end cap. The end cap assembly as a whole provides a tight seal for the cell.

摘要： A casing for cylindrical electrochemical cells, for example, alkaline cells or lithium cells. The casing is characterized by having a non-uniform wall thickness. The casing comprises a cylindrical body surface, an open end and an integrally formed closed bottom. A portion of the casing body forms the peripheral edge of the casing at the open end thereof. The casing body surface has a wall thickness which is less than the wall thickness of the casing bottom. The casing has a peripheral edge which has a wall thickness which is greater than the wall thickness of the body surface. The peripheral edge wall thickness is desirably about the same or greater than the wall thickness of the casing bottom. The casing is formed by subjecting a sheet of metal to a series of discrete punching steps. A partially formed cup is punched through a die cavity in each step thereby progressively drawing the cup to a progressively reduced diameter and increased length. This is accomplished desirably without changing any portion of the cup's wall thickness. The cup is subjected to a finishing step wherein the wall thickness of the body surface is reduced without altering the wall thickness of the bottom. The wall thickness of the peripheral edge remains the same or is increased in the finishing step.

摘要： An end cap seal assembly for an electrochemical cell such as an alkaline cell is disclosed. The end cap assembly comprises a convoluted end cap disk which may also function as a cell terminal and an underlying insulating disk also having a convoluted surface. The convoluted end cap disk has a downwardly extending wall with at least one aperture therethrough which preferably faces the ambient environment. The insulating disk has a downwardly extending wall forming a rupturable membrane which underlies and abuts the inside surface of the downwardly extending wall of the end cap. The rupturable membrane underlies and abuts the aperture in the downwardly extending wall of the end cap. When gas pressure within the cell exceeds a predetermined level the rupturable membrane pushes through said aperture and ruptures allowing gas to escape therefrom directly to the environment. A separate terminal plate may be welded to a portion of the top surface of the convoluted end cap. The conductive layer of a film-laminate condition tester may be connected to the terminal plate.

摘要： An end seal assembly for small sized cylindrical alkaline cells. The seal assembly eliminates the need for a separate end cap and also eliminates the need for an insulating washer which is normally included between the end cap and housing at the cell's open end in order to insulate the end cap from the housing. The seal assembly includes an insulating sealing disk which fits into the open end of the cell housing. The peripheral edge of the cell housing is crimped over the edge of the sealing disk to seal the cell. The sealing disk comprises an integral raised central boss which protrudes from the housing open end. An elongated current collector penetrates into the cell's interior through an aperture in the central boss. The head of the current collector is thus exposed to the external environment and forms an end (negative) terminal for the cell. The boss is wider than normal in order to prevent interlocking with heads from other like cells.

摘要： An end cap assembly is disclosed for sealing the open end of a cylindrical alkaline cell housing preferably having a diameter less than the diameter of AAA size cells. The end cap assembly is preferably intended for sealing AAAA (LR61) size cylindrical alkaline cells. The end cap assembly comprises a terminal end cap, an insulating sealing disk underlying said end cap, and an elongated current collector penetrating through an aperture in said insulating sealing disk. At least a portion of the insulating sealing disk lies within the cell housing to seal the open end thereof. The terminal end cap has a peripheral edge, preferably formed from a curved rib, which is locked within the peripheral edge of the insulating sealing disk. The end cap assembly does not require other metal disks held within the sealing and insulating disk. The insulating disk comprises a discontinuous skirt comprising a plurality of integral legs emanating downwardly into the cell interior from the peripheral edge of said insulating disk. The insulating sealing disk has an integrally formed rupturable membrane therein. The membrane ruptures when gas pressure within the cell exceeds a predetermined level.
