Wafer Alkaline Cell

US Patent:
7413828, Aug 19, 2008
Filed:
Mar 18, 2004
Appl. No.:
10/803438
Inventors:
Stuart M. Davis - Norfolk MA, US
Jonathan M. Boulton - North Attleboro MA, US
George Cintra - Holliston MA, US
Leslie Pinnell - Framingham MA, US
Charles E. O'Brien - Revere MA, US
Assignee:
The Gillette Company - Boston MA
International Classification:
H01M 6/04, H01M 6/12
US Classification:
429162, 429178, 429206, 429245
Abstract:
A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell. The opposing sides define a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises a single frame or two separate frames housing the anode and cathode material. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.

Wafer Alkaline Cell

US Patent:
7820329, Oct 26, 2010
Filed:
May 17, 2005
Appl. No.:
11/130670
Inventors:
Jonathan M. Boulton - North Attleboro MA, US
Stuart M. Davis - Norfolk MA, US
Charles E. O'Brien - Revere MA, US
Thomas C. Richards - Framingham MA, US
Assignee:
The Procter & Gamble Company - Cincinnati OH
International Classification:
H01M 6/04, H01M 6/12, H01M 4/64
US Classification:
429234, 429162, 429206
Abstract:
A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell and defining a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises preferably two separate plastic frames housing the anode and cathode material. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.

Wafer Alkaline Cell

US Patent:
7776468, Aug 17, 2010
Filed:
May 12, 2006
Appl. No.:
11/433523
Inventors:
Thomas C. Richards - Framingham MA, US
Stuart M. Davis - Norfolk MA, US
Jonathan M. Boulton - North Attleboro MA, US
Charles E. O'Brien - Revere MA, US
Yali Tang - Walpole MA, US
Assignee:
The Gillette Company - Boston MA
International Classification:
H01M 4/64, H01M 6/12, H01M 6/04
US Classification:
429162, 429209, 429241
Abstract:
A wafer alkaline cell of a laminar structure is disclosed. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. There may be one and desirably two anode frames securing an anode current collector sheet sandwiched therebetween. There may be a cathode frame bonded to the anode frames. There is an anode current collector sheet within the anode assembly. There is a cathode current collector sheet, optionally with an attached metal mesh embedded within the cathode assembly to assure good electrical contact with the cathode. Alternatively, a cathode endplate with spring action is employed which can move in response to changes of volume or pressure within the cathode, thereby maintaining good contact. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The cell is durable and preferably rigid and resists electrolyte leakage.
