    摘要： 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.

    摘要： Proton-conducting gel electrolytes with acid immobilized within a covalently cross-linked polymer network and composites containing the gel electrolytes provide low ionic resistance, minimize acid stratification, and prevent dendrite growth. The gel electrolytes can be formed from monomers dissolved in concentrated sulfuric acid and subsequently covalently cross-linked between the battery electrodes, or the covalently cross-linked gel electrolytes can be formed in water and subsequently exchanged into sulfuric acid. The mechanical properties of these gels can often be enhanced with the addition of silica powder, silica fiber, or other additives. In some cases, the covalently cross-linked gel electrolytes are formed in the presence of a conventional silica-filled polyethylene separator or within a low density fiber mat to provide mechanical reinforcement and controlled spacing between the battery electrodes. The covalently cross-linked gel electrolytes provide low ionic resistance, and increased power capacity of the battery, because the polymer networks can be formed at low concentrations (

    摘要： The invention relates to a grid arrangement for a plate-shaped battery electrode of an electrochemical accumulator comprising a frame and a grid arranged thereon, wherein the frame comprises at least one upper frame element having a connecting lug of the battery electrode disposed on its side facing away from the grid, wherein the grid comprises grid bars respectively surrounding cutouts of the grid, wherein the majority of the grid bars surrounding the cutouts are respectively disposed in a hexagonal arrangement such that the cutout situated in between forms a hexagon, characterized by one, some or all of the following a), b), c), d), e) features): a) the grid arrangement is coated with a pasty active mass on which liquid-absorbing material designed to absorb liquid electrolyte of the accumulator is disposed, b) the size of the hexagonal cutouts increases toward the upper frame element, c) the grid bars of all the hexagonal cutouts have the same width or the same cross-sectional area, d) none of the grid bars of the hexagonal cutouts run horizontal or parallel to the upper frame element, e) none of the grid bars of the hexagonal cutouts run vertical or perpendicular to the upper frame element. The invention further relates to an accumulator.
