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: 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 has a wheel shaped, molded plastic seal member of a unitary construction which includes a central cylindrical hub from which depend in outward radial sequence, an annular pressure vent, a boss, a downward projecting skirt, an annular flexure means for providing radial movement and an outer rim terminating at its periphery in a cylindrical wall. The pressure vent includes a thin membrane ring depending from the hub which joins the hub to an annular diaphragm. A hinge ring joins the periphery of the diaphragm to the boss. The seal member is designed so that the membrane ring fails primarily in shear at excessive cell pressure which makes the vent more reliable and easier to fabricate.

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: And end cap assembly and venting system therein for closing and sealing the open end of a cell housing. The end cap assembly comprises a sealing disk underlying an end cap, and a metal support disk between the end cap and the sealing disk. The metal support disk has a plurality of primary vent apertures and a plurality of secondary vent apertures through its surface. The primary vent apertures are spaced apart along a path located at a greater distance from the central longitudinal axis of the metal support disk than the secondary vent apertures. The insulating sealing disk may have a thinned portion therein forming an rupturable membrane circumventing the central hub of the sealing disk. The insulating sealing disk may have protrusions emanating from its top surface to deflect the membrane during rupture. The venting system releases internal gases rapidly from the cell in the event of an abusive or short circuit discharge.

摘要: An end cap seal assembly for an electrochemical cell such as an alkaline cell is disclosed. The end cap assembly comprises a metal support disk and underlying insulating sealing disk and a metal end cap overlying the metal support disk. The edge of the end cap and metal support disk is captured by the crimped edge of the insulating sealing disk. The support disk has a downwardly extending wall with at least one aperture therethrough. The insulating disk is preferably composed of a polyetherurethane material and may have a slanted downwardly extending wall forming a rupturable membrane which underlies and abuts the inside surface of the downwardly extending wall of the support disk. A portion of the rupturable membrane underlies and abuts the aperture in the downwardly extending wall of the support disk. The rupturable membrane pushes through said aperture and ruptures when gas pressure within the cell exceeds a predetermined level.

摘要: An alkaline cell having a flat housing, preferably of cuboid shape. The housing may be laser welded closed with a metal cover inserted as a part of an end cap assembly. A portion of an insulating seal may be held compressed between a sleeve extending from the metal cover and an anode current collector nail within the end cap assembly. The housing may include a vent mechanism, preferably a grooved vent, which can activate, when gas pressure within the cell reaches a threshold level typically between about 250 and 800 psig (1724×103 and 5515×103 pascal gage). The cell can have a supplemental laser welded vent which may activate at higher pressure levels.
