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.
