In accordance with at least selected embodiments or aspects, the present invention is directed to improved, unique, and/or high performance ISS lead acid battery separators, such as improved ISS flooded lead acid battery separators, ISS batteries including such separators, methods of production, and/or methods of use. The preferred ISS separator may include negative cross ribs and/or PIMS minerals. In accordance with more particular embodiments or examples, a 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.

Separators, batteries, systems, and methods for idle start stop vehicles

A battery separator for a lead/acid battery is resistant to oxidation arising from the use of water or acid containing contaminants, for example chromium (Cr), manganese (Mn), titanium (Ti), copper (Cu), and the like. The separator is a microporous membrane including a rubber. The rubber is no more than about 12% by weight of the separator. The rubber may be rubber latex, tire crumb, and combinations thereof. The rubber may be impregnated into the microporous membrane. The microporous membrane may be a microporous sheet of polyolefin, polyvinyl chloride, phenol-formaldehyde resins, cross-linked rubber, or nonwoven fibers. A method for preventing the oxidation and/or extending battery life of the separator is also included.

Oxidation protected separator

In at least select embodiments, the instant disclosure is directed to new or improved battery separators, components, materials, additives, surfactants, lead acid batteries, systems, vehicles, and/or related methods of production and/or use. In at least certain embodiments, the instant disclosure is directed to surfactants or other additives for use with a battery separator for use in a lead acid battery, to battery separators with a surfactant or other additive, and/or to batteries including such separators. In at least certain select embodiments, the instant disclosure relates to new or improved lead acid battery separators and/or systems including improved water loss technology and/or methods of manufacture and/or use thereof. In at least select embodiments, the instant disclosure is directed toward a new or improved lead acid battery separator or system with one or more surfactants and/or additives, and/or methods for constructing lead acid battery separators and batteries with such surfactants and/or additives for improving and/or reducing water loss from the battery.

Water loss separators used with lead acid batteries, systems for improved water loss performance, and methods of manufacture and use thereof

New or improved battery separators for lead-acid batteries that include a carbon or mineral additive applied to the separator. In possibly preferred embodiments, the battery separator may include engineered carbon materials applied to the battery separator to modify sulfate crystal formation while decreasing the detrimental consequences of excessive gas evolution into the negative electrode itself. In one embodiment, a method of enhancing the lead-acid energy storage performance of a lead-acid battery may include delivering carbon to the negative active material surface of the battery separator where the carbon may effectively enhance charge acceptance and improve life cycle performance of a lead-acid battery.

Lead-acid battery separators, electrodes, batteries, and methods of manufacture and use thereof

New, improved or optimized battery separators, components, batteries, industrial batteries, inverter batteries, batteries for heavy or light industrial applications, forklift batteries, float charged batteries, inverters, accumulators, systems, methods, profiles, additives, compositions, composites, mixes, coatings, and/or related methods of water retention, water loss prevention, improved charge acceptance, production, use, and/or combinations thereof are provided or disclosed. More particularly, the present invention is directed to one or more improved battery separators having various improvements that may result in 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))). The improved battery separators of the instant invention are particularly useful in or with industrial batteries, such as inverter batteries, batteries for heavy or light duty industrial applications, and so forth.

Battery separators, batteries and related methods

New or improved lead acid batteries with vapor pressure barriers and/or improved battery separators, as well as systems, vehicles, and/or methods of manufacture and/or use thereof are disclosed herein. In at least select embodiments, the instant disclosure provides new or improved lead acid batteries with a vapor pressure barrier. In at least select embodiments, the instant disclosure provides new or improved lead acid battery vapor pressure barriers along with new or improved battery separators, and/or methods of manufacture and/or use thereof. In at least select embodiments, the instant disclosure provides a new or improved lead acid battery with a vapor pressure barrier that reduces the water loss from the battery. In at least select embodiments, a method of reducing the water loss of a lead acid battery may include providing a vapor pressure barrier, such as a layer of oil, inside the lead acid battery along with an improved battery separator.

Vapor pressure barriers for lead acid batteries for improved water loss performance, separators, systems, and methods of manufacture and use thereof

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.
