Abstract
A recombinant battery separator pad is made from a mat of meltblown ultrafine polymer fibers, with the fibers being treated with an agent to render them permanently wettable. The fibers include at least ten percent of less than one micron, with the majority less than five microns. The mat has a liquid porosity of at least 90% and a surface area of at least 1.0 m.sup.2 /g.
