Patent number: 7491464Abstract: 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.Type: GrantFiled: June 8, 2004Date of Patent: February 17, 2009Assignee: The Gillette CompanyInventors: Brien Merrill, Derek Bobowick, Robert S. Ferrin, David Anglin, Mark Ashbolt, Scott Manning, Anthony Malgioglio, Alexander Shelekhin, Steven J. Specht, Matthew Sylvestre, Philip Trainer, Robert A. Yoppolo

Patent number: 7435395Abstract: An alkaline cell having a flat casing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising nickel oxyhydroxide. The casing can have a relatively small overall thickness, typically between about 5 and 10 mm, but may be larger. Cell contents can be supplied through an open end in the casing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes 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 vent mechanism such as a laser welded region on the surface of the casing which may activate at higher pressure levels.Type: GrantFiled: June 9, 2004Date of Patent: October 14, 2008Assignee: The Gillette CompanyInventors: Richard E. Durkot, Paul A. Christian, Dean MacNeil, James R. Costanzo, David Anglin, Mark Ashbolt, Derek Bobowick, Robert S. Ferrin, Anthony Malgioglio, Brien Merrill, Alexander Shelekhin, Steven J.

Patent number: 7294429Abstract: An alkaline cell having a flat housing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising MnO2. The housing can have a relatively small overall thickness, typically between about 5 and 10 mm. Cell contents can be supplied through an open end in the housing and an end cap assembly inserted therein to seal the cell. There can be a gap between separator and cathode for insertion of additional electrolyte. The end cap assembly includes 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 housing can have a relatively small overall thickness, typically between about 5 and 10 mm. Cell contents can be supplied through an open end in the housing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes a vent mechanism which can activate, when gas pressure within the cell reaches a threshold level typically between about 100 and 300 psig (6.89×105 and 20.69×105 pascal gage). The cell can have primary and supplemental vent mechanisms such as welded or thinned regions on the surface of the housing which may activate at different pressure levels. The cathode can be formed of a plurality of stacked slabs having aligned hollow centers with an elongated opening for anode material to be inserted therein.Type: GrantFiled: April 16, 2003Date of Patent: January 16, 2007Assignee: The Gillette CompanyInventors: David Anglin, Mark Ashbolt, Anthony Malgioglio, Alexander Shelekhin, Steven J.

Patent number: 6986969Abstract: An alkaline cell having a flat housing, preferably of cuboid shape. The cell can have an anode comprising zinc and a cathode comprising MnO2. The housing can have a relatively small overall thickness, typically between about 5 and 10 mm. Cell contents can be supplied through an open end in the housing and an end cap assembly inserted therein to seal the cell. The end cap assembly includes an insulating sealing member having a circumferential skirt which surrounds wide portions of the anode current collector. This provides a barrier between said wide portions of the current collector and the cell housing. The end cap assembly includes a vent mechanism which can activate, when gas pressure within the cell reaches a level typically between about 100 and 300 psig (6.89×105 and 20.69×105 pascal gage). The cathode can be formed of a plurality of stacked slabs having aligned hollow centers forming a central core with anode material placed therein. A separator is between anode and cathode.Type: GrantFiled: January 3, 2003Date of Patent: January 17, 2006Assignee: The Gillette CompanyInventors: David Anglin, Mark Ashbolt, Anthony Malgioglio, Alexander Shelekhin, Steven J.

Patent number: 6887618Abstract: An electrochemical cell generating hydrogen gas upon discharge, wherein the cell has an outer casing, a vent aperture passing through a wall of the casing, and a rupturable membrane covering the vent aperture. The outer casing preferably has a flat wall running along the cell's length and a vent aperture passing through the flat wall. The cell may typically be an alkaline cell in the shape of a cuboid. The rupturable membrane may be secured by a ring facing the inside surface of the flat wall of the casing in a position adjacent the vent aperture. The rupturable membrane is preferably of polysulfone. The membrane allows hydrogen gas to permeate therethrough to the environment and is rupturable if hydrogen gas within the cell interior builds up rapidly to a threshold pressure level. Optionally, a pointed puncture member extends into the vent aperture to assist membrane rupture.Type: GrantFiled: August 9, 2002Date of Patent: May 3, 2005Assignee: The Gillette CompanyInventors: Alexander Shelekhin, Robert S.
