    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.
