Abstract
The invention relates to a separator made of elastic plastic and suitable for use in a lead storage battery, and consisting of sheet material with an inner region and two peripheral regions and having ribs running in the longitudinal direction on at least one side, the ribs in the inner region being more widely spaced than those in the peripheral region, characterized in that at least the first 3 ribs in the peripheral region that are adjacent to the inner region have a cross-section essentially in the form of a triangle projecting from the level of the sheet material, with the base of the triangle on the sheet material, one side of the triangle facing the inner region and the other side facing the periphery, the side facing the inner region being longer than that facing the periphery, and to a lead storage battery containing such separators.
