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： 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： 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 method for producing a microporous material comprising the steps of: providing an ultrahigh molecular weight polyethylene (UHMWPE); providing a filler; providing a processing plasticizer; adding the filler to the UHMWPE in a mixture being in the range of from about 1:9 to about 15:1 filler to UHMWPE by weight; adding the processing plasticizer to the mixture; extruding the mixture to form a sheet from the mixture; calendering the sheet; extracting the processing plasticizer from the sheet to produce a matrix comprising UHMWPE and the filler distributed throughout the matrix; stretching the microporous material in at least one direction to a stretch ratio of at least about 1.5 to produce a stretched microporous matrix; and subsequently calendering the stretched microporous matrix to produce a microporous material which exhibits improved physical and dimensional stability properties over the stretched microporous matrix.

摘要： Improved battery separators are disclosed herein for use in flooded lead-acid batteries, and in particular enhanced flooded lead-acid batteries. The improved separators disclosed herein provide for enhanced electrolyte mixing and substantially reduced acid stratification. The improved flooded lead-acid batteries may be advantageously employed in applications in which the battery remains in a partial state of charge, for instance in start/stop vehicle systems. Also, improved lead-acid batteries, such as flooded lead-acid batteries, improved systems that include a lead-acid battery and a battery separator, improved battery separators, improved vehicles including such systems, and/or methods of manufacture and/or use may be provided.

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.
