Abstract
A battery separator in the form of a nonwoven fibrous web of water dispersible fibers incorporates up to 65% by weight of fibers having a high cross-sectional aspect ratio. The high aspect ratio fibers include collapsible hollow fibers and ribbon fibers that have a width five to ten times greater than their thickness. These fibers provide reduced thickness at the same basis weight and a synergistic reduction in shrinkage when combined with lower denier solid fibers.
