摘要： A multilayer deep cycle battery separator comprising at least two layers of an automotive-sized separator bonded or welded together. The automotive-sized separator layers include a backweb having a backweb thickness between 6 to 10 mils, an overall thickness of between 25 to 65 mils, and a rib base width of between 20 to 35 mils. The automotive-sized separator layers also have an extraction time of between 45 to 75 seconds, thereby providing an overall extraction time of less than a standard deep cycle battery separator.

摘要： A separator for a lead acid battery is a porous membrane having a positive electrode face and a negative electrode face. A plurality of longitudinally extending ribs, a plurality of protrusions or a nonwoven material may be disposed upon the positive electrode face. A plurality of transversely extending ribs are disposed upon the negative electrode face. The transverse ribs disposed upon the negative electrode face are preferably juxtaposed to a negative electrode of the lead acid battery, when the separator is placed within that battery.

摘要： In accordance with at least certain embodiments of the present invention, a novel concept of utilizing PIMS minerals as a filler component within a microporous lead-acid battery separator is provided. In accordance with more particular embodiments or examples, the 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.

摘要： A method for producing a microporous membrane comprising the steps of: providing an ultrahigh molecular weight polyethylene (UHMWPE); providing a filler; providing a processing plasticizer; mixing UHMWPE, filler and the processing plasticizer together to form a mixture having a weight ratio of filler to UHMWPE of from 1:9 to 15:1 by weight; extruding the mixture to form a sheet from the mixture; processing said sheet where processing is selected from the group consisting of: calendaring, casting or blowing; extracting all or part of the processing plasticizer from the sheet to produce a matrix comprising UHMWPE and the filler distributed throughout the matrix, to produce a microporous matrix sheet; and optionally calendaring the microporous matrix sheet to produce a microporous membrane.
