    摘要： 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.

    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 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： An exemplary hybrid battery separator is provided with a porous sheet with a folded bottom edge and joined lateral edges that form a pocket. The folded bottom edge may have one or more openings or slits. The hybrid separators of the present disclosure are particularly useful for flat-plate cycling batteries. The separators of the present disclosure may effectively enhance the battery re-chargeability and the backup time. In addition, the separators of the present disclosure may contribute to the reduction of water loss in the battery, lowering the maintenance needs in service. It is expected that batteries having the separators of the present disclosure may be useful in various applications, such as in inverters, golf carts, as well as solar and traction applications.

    摘要： The present disclosure or invention is directed to novel or improved separators for a variety of lead acid batteries and/or systems. In addition, exemplary embodiments disclosed herein are directed to novel or improved battery separators, separator profiles, separator and electrode assemblies incorporating the same, battery cells incorporating the same, batteries incorporating the same, systems incorporating the same, and/or methods of manufacturing and/or of using the same, and/or the like, and/or combinations thereof. For example, disclosed herein are exemplary embodiments of improved electrode plate and separator assemblies (400) for lead acid batteries, improved lead acid cells or batteries incorporating the improved assemblies, systems or vehicles incorporating the improved assemblies (400) and/or batteries (100), and methods related thereto. The electrode plate (200, 201) may have a grid (202) of a stamped, cast, or expanded metal manufacturing process. The grid (202) may have a non-uniform application of active material (203).
