The instant invention is directed to a battery separator. The separator is formed from a thin sheet of acid-stable, porous material and has a first and a second major face with a plurality of separate, continuous, open channels on each face such that each channel on each major face defines a separation between two channels on the other major face. Further, each channel defines an imaginary median line with at least some portions of at least some channels extending laterally with respect to the imaginary median line, and every portion of each channel is capable of being at an acute angle of not greater than 70 degrees from an imaginary vertical line orientated from bottom to top of a battery containing the separator sheet. |
