Battery separator and method of making |
摘要 |
A battery separator for use in flooded cell type lead acid batteries comprising a backweb of a porous, acid resistant, embossable material with a plurality of major ribs and submini-ribs extending from at least one planar surface of the backweb. The ribs are located across the width of the backweb and extend in a direction substantially parallel to the longitudinal edges of the backweb. Each major rib overlies at least one submini-rib and is an embossed corrugated structure comprised of alternating ridges and furrows. The ridges and furrows are in non-parallel alignment to the longitudinal dimension of the separator, and preferably perpendicular thereto. The major ribs are formed on a battery separator backweb having a plurality of submini-ribs extending from at least one planar surface thereof by passing the backweb through the nip formed by a pair of opposed embossing rollers and embossing the backweb in the area of at least one submini-rib. |
