BATTERY SEPARATOR WITH POROUS BACKWEB AND RIBBING |
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 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 dimension of the backweb. Each rib 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 ribs are formed on a substantially flat battery separator backweb by passing the backweb through the nip formed by a pair of opposed embossing rollers. |
