摘要： Disclosed herein are improved separators for lead acid batteries, lead acid batteries, systems, vehicles, and/or methods and/or uses for the same. The separators may include a porous membrane and a nucleation additive. In accordance with at least select embodiments, the present disclosure or invention may address current issues or needs, and/or may provide an improved separator and/or battery which overcomes the current issues or problems, for instance, by providing batteries mitigating the formation of dendrites, having improved charge acceptance, and/or having improved cycling performance.

摘要： Disclosed herein are exemplary embodiments of improved separators for lead acid batteries, improved lead acid batteries incorporating the improved separators, and vehicles, devices, or systems incorporating the same. A lead acid battery separator is provided with a porous membrane with a plurality of ribs extending from a surface thereon. The plurality of ribs preferably includes both positive ribs and negative ribs having similar heights. The ribs are provided with a plurality of discontinuous peaks arranged such as to provide resilient support for the porous membrane in order to resist forces exerted by active material swelling and thus mitigate the effects of acid starvation associated with such swelling, and increasing the acid availability at the electrodes. A lead acid battery is further provided that incorporates the provided separator. Such a lead acid battery may be a flooded lead acid battery, an enhanced flooded lead acid battery, a gel battery, an AGM battery, and may be provided as operating in a partial state of charge. Systems incorporating such a lead acid battery are also provided, such as a vehicle or any other energy storage system, such as solar or wind energy collection. Other exemplary embodiments are provided such as to have any one or more of the following: increased or improved acid availability, reduced or mitigated acid starvation, and other improvements.

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.
