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.
A battery separator for reduced water-loss comprising a surfactant in or on the battery separator, wherein the surfactant comprises an ethylene oxide/propylene oxide block copolymer, having an HLB from 1 to 1.5 and at least one of metallic zinc, bismuth, silver, selenium, and cadmium in or on the battery separator.
