Battery separators made of a wettable, uniform mat of melt blown fibers. The melt blown fibers are thermally bonded to one another. These fibers are made of a thermoplastic material. The fibers have a diameter in the range of 0.1 to 13 microns (mu) and lengths greater than 12 millimeters (mm). The mat has a basis weight ranging from 6 to 160 grams per square meter (g/m<2>), a thickness of less than 75 microns (mu), and an average pore size of 0.3 to 50 microns (mu). |
