摘要： A battery separator including a porous membrane with a surfactant coating on at least one side thereof is described. The surfactant coating may include a non-ionic surfactant in a low amount, a blend of a non-ionic surfactant and an ionic surfactant, or the surfactant coating may contain only an ionic surfactant. Battery may exhibit improved properties such as reduced grid corrosion, a lower black residue rating, longer discharge life, lower water loss, improved charge acceptance, longer life.

摘要： In accordance with at least selected embodiments or aspects, the present invention is directed to improved, unique, and/or complex performance lead acid battery separators, such as improved flooded lead acid battery separators, batteries including such separators, methods of production, and/or methods of use. The preferred battery separator of the present invention addresses and optimizes multiple separator properties simultaneously. It is believed that the present invention is the first to recognize the need to address multiple separator properties simultaneously, the first to choose particular multiple separator property combinations, and the first to produce commercially viable multiple property battery separators, especially such a separator having negative cross ribs.
摘要翻译：根据至少选定的实施例或方面，本发明涉及改进的，独特的和/或复杂的铅酸电池分离器，例如改进的浸渍铅酸电池隔板，包括这种隔板的电池，生产方法和/ 或使用方法。本发明优选的电池隔板同时处理和优化多个分离器的特性。相信本发明首先认识到需要同时解决多个分离器特性，首先选择特定的多分离器性质组合，以及首先产生商业上可行的多特性电池分离器，特别是这种具有负交叉的分离器肋骨。
