Separator for electrode of lead accumulator, comprises disk-shaped base element, which has multiple spacers with multiple burl-like projections that are distributed over disk surface

摘要

The separator comprises a disk-shaped base element (1), which has multiple spacers with multiple burl-like projections (2,3,4,5,6) distributed over a disk surface. The projections are arranged in such a manner, that the flow behavior of lead contained in an electrolyte, is controlled during loading and unloading of a lead accumulator.
