Disclosed herein are exemplary embodiments of improved electrode plate and separator assemblies () for lead acid batteries, improved lead acid cells or batteries incorporating the improved assemblies, systems or vehicles incorporating the improved assemblies () and/or batteries (), and methods related thereto. The electrode plate () may have a grid () of a stamped, cast, or expanded metal manufacturing process. The grid () may have a non-uniform application of active material (). The separators () preferably provide a support structure for resisting or mitigating any plate warping or plate deflection.

Lead acid battery separators, warp resistant separators, batteries, systems, and related methods

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.

Separators for enhanced flooded batteries, batteries, and related methods

Disclosed herein are novel or improved fibrous layers, composites, composite separators, separators, composite mat separators, composite mat separators containing fibers and silica particles, battery separators, lead acid battery separators, and/or flooded lead acid battery separators, and/or batteries, cells, and/or methods of manufacture and/or use of such fibrous layers, composites, composite separators, separators, battery separators, lead acid battery separators, cells, and/or batteries. In addition, disclosed herein are methods, systems, and battery separators for enhancing battery life, reducing internal resistance, reducing metalloid poisoning, reducing acid stratification, and/or improving uniformity in at least enhanced flooded batteries.

Composite layers or separators for lead acid batteries

Improved battery separators, batteries, and systems, as well as methods relating thereto are disclosed herein for use in various lead acid batteries such as valve-regulated lead acid (VRLA) batteries that include one or more AGM layers. The improved battery separators described herein may provide a battery system with an advantage of a significantly decreased acid filling time and a significantly increased acid filling speed. Various improved batteries, methods and systems are described herein using such improved battery separators that increase acid filling speed and decrease acid filling time for a VRLA battery.

Apertured polymeric films for use as a liquid permeable facing material on absorbent products such as diapers and sanitary napkins is textured by a dual embossing process. The film is preferably embossed first with a pronounced, textile-like pattern, then embossed with a finely engraved finish roll to produce a thin, smooth film with a matte finish while retaining the appearance of the previously embossed pattern. The twice embossed film is soft, conformable, and more comfortable against the skin. The embossing sequence may be reversed for some applications.
