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.
A lead acid battery separator comprising a microporous membrane comprising polymer, oil, and a filler, said filler comprising silica and at least one phosphate induced metal stabilization (PIMS) mineral for reducing the lead concentration in the acid of the battery, the PIMS mineral comprises hydroxyapatite, the filler comprises 5-30% of hydroxyapatite, and the PIMS mineral is extruded with the polymer and the silica to polymer ratio is from 3.0/1.0 to 5.0/1.0.
