摘要： The invention is directed to a method of forming a pip protrusion at the closed end of a cylindrical casing of an electrochemical cell. The cell is preferably an alkaline cell having an anode comprising zinc, a cathode comprising manganese dioxide, and an alkaline electrolyte. The method of the invention is directed to forming the pip protrusion at the closed end of the casing so that the pip protrusion becomes an integral part of the casing. In an alkaline cell the pip protrusion becomes the cell's positive terminal. The method of the invention involves inserting cathode material into the casing through the open end thereof and then forcing an elongated plunger having a diameter less than the inside diameter of casing into the cathode material while providing means for preventing the cathode material form rising more than a predetermined level with the casing. The force of the plunger causes the cathode material to become compacted while simultaneously causing a pip protrusion to form at the closed end of the casing.

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.
