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： In at least one embodiment, a separator is provided with a fibrous mat for retaining the active material on an electrode of a lead-acid battery. New or improved mats, separators, batteries, methods, and/or systems are also disclosed, shown, claimed, and/or provided. For example, in at least one possibly preferred embodiment, a composite separator is provided with a fibrous mat for retaining the active material on an electrode of a lead-acid battery. In at least one possibly particularly preferred embodiment, a PE membrane separator is provided with at least one fibrous mat for retaining the active material on an electrode of a lead-acid battery. In accordance with at least certain embodiments, aspects and/or objects, the present invention, application, or disclosure may provide solutions, new products, improved products, new methods, and/or improved methods, and/or may address issues, needs, and/or problems of PAM shedding. NAM shedding, electrode distortion, active material shedding, active material loss, and/or physical separation, electrode effectiveness, battery performance, battery life, and/or cycle life, and/or may provide new battery separators, new battery technology, and/or new battery methods and/or systems that address the challenges arising from current lead acid batteries or battery systems, especially new battery separators, new battery technology, and/or new battery methods and/or systems adapted to prevent or impede the shedding of active material from the electrodes, preferably or particularly in enhanced flooded lead acid batteries, PSoC batteries, ISS batteries, ESS batteries, and/or the like.

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 (storage) battery is made from a thermoplastic sheet material. The sheet material has a central region flanked by peripheral regions. The central region includes a plurality of longitudinally extending ribs that are integrally formed from the sheet material. The peripheral regions are free of ribs and may include a densified structure. Also disclosed are a method of producing the foregoing separator, an envelope separator made from the sheet material, and a method of making the envelope separator.
