摘要： A battery separator (116) includes dispersed throughout its porous structure a benzaldehyde derivative as a hydrogen-evolution inhibitor to improve the cycle life of a lead-acid battery (100) containing the battery separator. The disclosed battery separator is particularly useful in a deep cycle battery installed in an electric vehicle, such as a golf car or a floor scrubber. Preferred embodiments of the disclosed battery separator are based on a microporous polyethylene separator material or on an absorptive glass mat (AGM) separator material having a porous structure through which the hydrogen-evolution inhibitor is dispersed. Vanillin (4- hydroxy 3-methoxybenzaldehyde) compound is a preferred derivative of benzaldehyde that interacts with antimony present in the battery electrode plates to suppress hydrogen gas evolution. Vanillin dispersed throughout the porous structure exhibits strong antimony-suppression behavior and thereby maintains hydrogen evolution inhibitor properties during handling and manipulation of the battery separator.
摘要翻译：电池隔板（116）包括在整个多孔结构体中分散苯甲醛衍生物作为析氢抑制剂，以改善含有电池隔膜的铅酸电池（100）的循环寿命。所公开的电池隔板在安装在诸如高尔夫球车或地板洗涤器的电动车辆中的深循环电池中特别有用。所公开的电池隔板的优选实施方案基于微孔聚乙烯隔板材料或具有分散氢析出抑制剂的多孔结构的吸收玻璃垫（AGM）隔板材料。香草醛（4-羟基-3-甲氧基苯甲醛）化合物是与电池电极板中存在的锑相互作用的苯甲醛的优选衍生物，以抑制氢气逸出。分散在整个多孔结构中的香草醛表现出强烈的锑抑制行为，从而在电池分离器的处理和操作过程中保持析氢抑制剂的性质。

摘要： A microporous polyethylene battery separator material (212), for use in a flooded-cell type lead-acid battery, benefits from increased porosity, enhanced wettability, and exceptionally low electrical resistance when an electrolyte-soluble pore former is employed in the manufacturing process. The pore former (210) is soluble in electrolytic fluid and therefore dissolves in-situ in sulfuric acid during battery assembly. The dissolution of the pore former leaves behind additional, larger voids (220) in the separator material and thereby enhances ionic diffusion and improves battery performance.

摘要： A microporous silica-filled polyolefin separator (80) has a material composition that includes a fraction of cured rubber powder exhibiting low or no porosity. The cured rubber powder is a material derived from one or both of passenger and truck tires. The cured rubber powders exhibit the properties of increasing hydrogen evolution overpotential on the negative lead electrode and of decreasing the effect of antimony deposited on the negative electrode of the lead-acid battery. Incorporation of these cured rubber powders into the formulation of a microporous silica-filled polyethylene separator results in improved electrochemical properties in deep-cycle lead-acid batteries.
摘要翻译：微孔二氧化硅填充的聚烯烃分离器（80）具有包含表现出低孔隙率或无孔隙率的固化橡胶粉末的分数的材料组成。固化的橡胶粉是来自客车和卡车轮胎中的一个或两个的材料。固化的橡胶粉末具有在负极铅电极上增加析氢超电势并降低沉积在铅酸电池负极上的锑的作用的性质。将这些固化的橡胶粉末掺入微孔二氧化硅填充的聚乙烯隔膜的配方中导致在深循环铅酸电池中改善的电化学性能。
