    摘要： 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.

    摘要： In accordance with at least selected embodiments or aspects, the present invention is directed to improved, unique, and/or complex performance lead acid battery separators, such as improved flooded lead acid battery separators, batteries including such separators, methods of production, and/or methods of use. The preferred battery separator of the present invention addresses and optimizes multiple separator properties simultaneously. It is believed that the present invention is the first to recognize the need to address multiple separator properties simultaneously, the first to choose particular multiple separator property combinations, and the first to produce commercially viable multiple property battery separators, especially such a separator having negative cross ribs.

    摘要： 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.

    摘要： A separator is provided with a novel construction and/or a combination of improved properties. Batteries, methods, and systems associated therewith are also provided. In certain embodiments, novel or improved separators, battery separators, enhanced flooded battery separators, batteries, cells, and/or methods of manufacture and/or use of such separators, battery separators, enhanced flooded battery separators, cells, and/or batteries are provided. In addition, there is disclosed herein methods, systems, and battery separators having a reduced ER, improved puncture strength, improved separator CMD stiffness, improved oxidation resistance, reduced separator thickness, reduced basis weight, and any combination thereof. In accordance with at least certain embodiments, separators are provided in battery applications for flat-plate batteries, tubular batteries, vehicle SLI, and HEV ISS applications, deep cycle applications, golf car or golf cart, and e-rickshaw batteries, batteries operating in a partial state of charge (“PSOC”), inverter batteries; and storage batteries for renewable energy sources, and any combination thereof.
