Title: IMPROVED SEPARATORS FOR ENHANCED FLOODED BATTERIES, BATTERIES, AND RELATED METHODS
Abstract:
Disclosed are improved separators, battery separators, enhanced flooded battery separators, batteries, cells, and/or methods of manufacture and/or use thereof; battery separators for enhanced flooded batteries; methods, systems and battery separators for enhancing battery life, reducing internal electrical resistance, increasing cold cranking amps, and/or improving uniformity in at least enhanced flooded batteries; a separator for enhanced flooded batteries having performance enhancing additives or coatings, improved fillers, and/or fillers with increased friability, having increased ionic diffusion, decreased tortuosity, increased wettability, reduced oil content, reduced thickness, decreased electrical resistance, and/or increased porosity, and where the use thereof reduces the water loss, lowers acid stratification, lowers the voltage drop, and/or increases the CCA of the battery; and/or separators that 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, and/or a shish-kebab structure or morphology.
