    摘要： 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.

    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： 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.

    摘要： New, improved or optimized battery separators, Z wrap separators, Z wrap serrated rib separators, Z wrap serrated rib separators for tubular batteries, components, cells, modules, systems, batteries, tubular batteries, industrial batteries, inverter batteries, batteries for heavy or light industrial applications, forklift batteries, float charged batteries, inverters, accumulators, methods, profiles, additives, compositions, composites, mixes, coatings, and/or related methods of Z wrapping separators, Z wrapping separators on electrodes of tubular batteries, water retention, water loss prevention, improved charge acceptance, production, use, and/or related Z wrapping equipment, and/or combinations thereof. More particularly, the present invention is directed to one or more improved battery separators having various improvements that may result in automated separator Z wrapping, automated Z wrapped cell module production, automated tubular battery production, decreased water loss for a battery in which such a separator is incorporated, enhanced charge acceptance, or combinations thereof. Additionally, the present invention relates to one or more improved battery separators having various improvements with regard to shape, and/or physical profile, and/or chemical(s), additives, mixes, coatings, and/or the like used to make such battery separators (such as oil(s), and/or chemical additive(s) or agents used to coat, finish or improve such battery separators (such as surfactant(s))). Furthermore, the present invention relates to one or more one or more improved separator configurations, Z wrap cell modules, Z wrap tubular electrodes or z wrap gauntlet covered tubular electrodes, and/or battery electrode and separator assembly configurations providing for automation, better acid mixing and/or reduced acid stratification over prior sleeves, pockets, or envelope separator configurations, improved battery electrode and separator assembly configurations and/or manufacturing methods and/or manufacturing equipment. The improved Z wrap battery separators of the instant invention are particularly useful in or with tubular batteries, industrial batteries, such as inverter batteries, batteries for heavy or light industry, and/or the like.
