US Patent:

7517370, Apr 14, 2009
Filed:

Oct 21, 2004
Appl. No.:

10/576427
Inventors:

Ralph A. Petersen - West Allis WI, US
Ross A. Henning - Colgate WI, US
Assignee:

Johnson Controls Technology Company - Holland MI
International Classification:

H01M 10/04
B05D 5/12
US Classification:

296235, 4271261, 4271265, 141 11
Abstract:

A method of making a battery plate includes mixing particles of tetrabasic lead sulfate with leady oxide to form a paste material. The particles have an average spherical particle diameter of less than 2. 5 micrometers. The method also includes providing at least a portion of the paste material on a battery grid curing the battery grid and paste material at a temperature of less than approximately 48 degrees Celsius to produce a battery plate having a cured paste thereon.

Apparatus For Production Of A Battery Paste

US Patent:

52903591, Mar 1, 1994
Filed:

Dec 6, 1991
Appl. No.:

7/804845
Inventors:

Matthew A. Coonen - Pewaukee WI
Ralph A. Petersen - West Allis WI
Conrad E. Weinlein - Mequon WI
Assignee:

Globe-Union Inc. - Milwaukee WI
International Classification:

B05C 1100
US Classification:

118712
Abstract:

A process for making a battery paste includes steps of forming an active material in an aqueous slurry, then dewatering the slurry to form a battery paste. In one described embodiment, a slurry containing one or more basic lead sulfates suitable for use as the active material in lead-acid battery electrodes is formed in a continuously stirred tank reactor (36). The slurry is withdrawn from the reactor (36) and fed to a belt press (67) which reduces the moisture content of the slurry to the desired level. Battery pastes produced according to the invention may be fed continuously to a paster (89) for mass production of positive and negative battery plates from grids (91).

US Patent:

51496062, Sep 22, 1992
Filed:

Mar 12, 1991
Appl. No.:

7/667878
Inventors:

Norma K. Bullock - Pewaukee WI
Ralph A. Petersen - West Allis WI
Assignee:

Globe-Union Inc. - Milwaukee WI
International Classification:

H01M 1004
US Classification:

429228
Abstract:

Improved formation efficiencies for positive pasted plates used in lead-acid batteries are provided by treatment of the positive plates with a stabilized aqueous alkaline persulfate solution to effect the conversion of lead monoxide to lead dioxide. Use of the alkaline persulfate solution enhances both formation and initial performance of the fabricated batteries. A stabilizing agent is added to the alkaline persulfate solution to stabilize the lead sulfate and basic lead sulfates in the paste. A preferred method for producing positive plates of a lead-acid battery comprises the steps of (a) heating the pasted plate, (b) spray coating with or dipping the plate in a persulfate solution, and (c) reheating the plate to accelerate the reaction of lead monoxide with persulfate to form lead dioxide. The persulfate treatment may be applied to uncured pasted plates and used with plate paste containing free lead, and the spray-coating procedure offers an easy and efficient manufacturing step.
