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 a compound having the following structures:

where n is an integer from 0 to 10, m is an integer from 0 to 10, n and m are the same or different, q is an integer from 0 to 10, r is an integer from 0 to 10, s is an integer from 0 to 10, and q, r, and s are the same or different, R1 is H, a C1 to C10 linear or branched, saturated or unsaturated alkyl group, a C1 to C10 fatty alcohol, a C1 to C10 alcohol, or an aromatic group, and R2 is H, a C1 to C10 linear or branched, saturated or unsaturated alkyl group, a C1 to C10 linear or branched, saturated or unsaturated fatty alcohol, a C1 to C10 linear or branched, saturated or unsaturated alcohol, or an aromatic group, n and m are the same or different, R1 and R2 are the same or different, R3 is hydrogen or methyl or a C1 to C5 alkyl group, R4 is hydrogen or methyl or a C1 to C5 alkyl group R3 and R4 are the same or different, and X is a negatively charged groups such as SO3—, COO—, PO4-2, and the like; and also a positively charged counterion. When the separator described herein is used in a battery, the 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, etc.

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.
