Patent Images
1. A battery separator comprising:
- a backweb of porous, acid resistant, embossable material, said backweb having substantially parallel longitudinal side edges, a longitudinal axis parallel to said side edges, a width dimension perpendicular to said longitudinal side edges, and upper and lower planar surfaces;
said separator having a plurality of submini-ribs protecting from at least one planar surface of said backweb, said submini-ribs extending substantially parallel to the longitudinal axis of said backweb;
said separator having a plurality of major ribs extending across the width of said backweb diagonally to the longitudinal axis of said backweb, each said major rib being embossed into a plurality of said submini-ribs, each of said major ribs being comprised of lanes of a corrugated structure having substantially parallel side edges with alternating ridges and furrows extending therebetween.

Abstract
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 across the width of the backweb from at least one planar surface of the backweb. The submini-ribs extend in a direction substantially parallel to the longitudinal axis of the backweb. The major ribs extend in a direction that is diagonal to the longitudinal axis of the backweb. Each major rib is an embossed corrugated structure comprised of alternating ridges and furrows. The separator is particularly useful in a flooded cell type lead acid battery having tubular plates.
