摘要： A flooded lead acid battery and a vehicle comprising the same are described herein. The flooded lead acid battery comprises an electrode array, comprising one or more negative plates and one or more positive plates alternately arranged and interleafed with one another. In some embodiments, a negative plate is wrapped or enveloped with a fibrous mat, and a porous membrane is wrapped or enveloped about an adjacent positive electrode. In some embodiments, a fibrous mat is at least partially integrated into a negative plate, and a porous membrane is enveloped about either the negative plate with the fibrous mat partially integrated therein or around an adjacent positive plate. In other embodiments, a negative plate is enveloped with a porous membrane having ribs, and a fibrous mat is present between the wrapped negative plate and the porous membrane enveloping the negative plate. Methods, systems, and vehicles utilizing the disclosed batteries are also provided.

摘要： Improved battery separators are disclosed herein for use in flooded lead-acid batteries, and in particular enhanced flooded lead-acid batteries. The improved separators disclosed herein provide for enhanced electrolyte mixing and substantially reduced acid stratification. The improved flooded lead-acid batteries may be advantageously employed in applications in which the battery remains in a partial state of charge, for instance in start/stop vehicle systems. Also, improved lead-acid batteries, such as flooded lead-acid batteries, improved systems that include a lead-acid battery and a battery separator, improved battery separators, improved vehicles including such systems, and/or methods of manufacture and/or use may be provided.

摘要： A battery separator has performance enhancing additives or coatings, fillers with increased friability, increased ionic diffusion, decreased tortuosity, increased wettability, reduced oil content, reduced thickness, decreased electrical resistance, and/or increased porosity. The separator in a battery reduces the water loss, lowers acid stratification, lowers the voltage drop, and/or increases the CCA. The separators include or exhibit performance enhancing additives or coatings, increased porosity, increased void volume, amorphous silica, higher oil absorption silica, higher silanol group silica, reduced electrical resistance, a shish-kebab structure or morphology, a polyolefin microporous membrane containing particle-like filler in an amount of 40% or more by weight of the membrane and ultrahigh molecular weight polyethylene having shish-kebab formations and the average repetition periodicity of the kebab formation from 1 nm to 150 nm, decreased sheet thickness, decreased tortuosity, separators especially well-suited for enhanced flooded batteries.

摘要： A separator for a lead acid battery is a porous membrane having a positive electrode face and a negative electrode face. A plurality of longitudinally extending ribs, a plurality of protrusions or a nonwoven material may be disposed upon the positive electrode face. A plurality of transversely extending ribs are disposed upon the negative electrode face. The transverse ribs disposed upon the negative electrode face are preferably juxtaposed to a negative electrode of the lead acid battery, when the separator is placed within that battery.

摘要： New or improved battery separators for lead-acid batteries that include a carbon or mineral additive applied to the separator. In possibly preferred embodiments, the battery separator may include engineered carbon materials applied to the battery separator to modify sulfate crystal formation while decreasing the detrimental consequences of excessive gas evolution into the negative electrode itself. In one embodiment, a method of enhancing the lead-acid energy storage performance of a lead-acid battery may include delivering carbon to the negative active material surface of the battery separator where the carbon may effectively enhance charge acceptance and improve life cycle performance of a lead-acid battery.

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.
