    Abstract: 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). The separators (300) provide a support structure for resisting or mitigating any plate warping or plate deflection.

    Abstract: 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.

    Abstract: 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.
