Jeffrey K. Chambers - Philpot KY, US
Mohammed Naiha - Chatenois, FR
Tejas R. Shah - Owensboro KY, US

International Classification:

H01M 2/14

US Classification:

429247, 427 58

Abstract:

A lead-acid battery separator comprised of a porous membrane substrate having a front surface and a back surface and said front surface having a plurality of ribs. To enhance the substrate's stiffness, one or more coatings of a stiffening material may be adhered to the ribs on the substrate's surface.

Abstract:

In accordance with at least selected embodiments or aspects, the present invention is directed to improved, unique, and/or high performance ISS lead acid battery separators, such as improved ISS flooded lead acid battery separators, ISS batteries including such separators, methods of production, and/or methods of use. The preferred ISS separator may include negative cross ribs and/or PIMS minerals. In accordance with more particular embodiments or examples, a PIMS mineral (preferably fish meal, a bio-mineral) is provided as at least a partial substitution for the silica filler component in a silica filled lead acid battery separator (preferably a polyethylene/silica separator formulation). In accordance with at least selected embodiments, the present invention is directed to new or improved batteries, separators, components, and/or compositions having heavy metal removal capabilities and/or methods of manufacture and/or methods of use thereof.

International Classification:

H01M 50/411
H01M 10/12
H01M 50/44
H01M 50/403

Abstract:

A battery separator for a lead/acid battery is resistant to oxidation arising from the use of water or acid containing contaminants, for example chromium (Cr), manganese (Mn), titanium (Ti), copper (Cu), and the like. The separator is a microporous membrane including a rubber. The rubber is no more than about 12% by weight of the separator. The rubber may be rubber latex, tire crumb, and combinations thereof. The rubber may be impregnated into the microporous membrane. The microporous membrane may be a microporous sheet of polyolefin, polyvinyl chloride, phenol-formaldehyde resins, cross-linked rubber, or nonwoven fibers. A method for preventing the oxidation and/or extending battery life of the separator is also included.

H01M 50/431
H01M 50/463
H01M 10/12

Abstract:

A battery separator for a lead acid battery addresses the issues of acid stratification and separator oxidation arising from contaminants. The separator includes a microporous membrane and a diffusive mat affixed thereto. The diffusive mat has a three hour wick of: at least about 2.5 cm. The diffusive mat may be made of synthetic fibers, glass fibers, natural fibers, and combinations thereof. The diffusive mat may include silica. The separator may include a rubber.

International Classification:

H01M 10/12
H01M 2/16
H01M 2/14
H01M 4/02

Abstract:

New or improved battery separators for lead-acid batteries that include a carbon or mineral additive applied to the separator. In possibly preferred embodiments, the battery separator may include engineered carbon materials applied to the battery separator to modify sulfate crystal formation while decreasing the detrimental consequences of excessive gas evolution into the negative electrode itself. In one embodiment, a method of enhancing the lead-acid energy storage performance of a lead-acid battery may include delivering carbon to the negative active material surface of the battery separator where the carbon may effectively enhance charge acceptance and improve life cycle performance of a lead-acid battery.
