Filed:

Jun 1, 1988

Appl. No.:

7/200977

Inventors:

Chris Morris - Austin TX

Assignee:

Electrosource, Inc. - Austin TX

International Classification:

H01M 648
H01M 600

US Classification:

296231

Abstract:

An improvement in lead-acid batteries is disclosed. The improvement is directed toward construction of a lead-acid rechargeable battery in which bipolar positive and negatives plates (biplates) share the same grid or substrate. According to the present invention, such biplates are stacked upon each other, separated by interleaved, highly porous glass mat separators. These substratea positioned between the positive and negative plate areas act as electrical connections attaching the plates to terminals of the battery. The battery case cover is used to provide compressive force on the biplates and separators.

Abstract:

A lead-oxide paste mix for use as an active material superimposed upon the plates of a lead-acid rechargeable battery. Battery grades of oxides of lead are mixed with a dilute solution of hydrogen peroxide, either alone or with additives and/or expanders. The resultant paste offers such advantages as reduced curing and drying times and/or the elimination of the need for curing and drying, lower dry active material weights and improved cohesion when compared to conventional pastes manufactured from leady oxides, sulfuric acid, and water.
