ABSTRACT:
A tubular plate for electrical lead acid accumulators comprises tubes formed of porous fibrous material having a shape such that the ratio of volume to surface area of active material is no greater than 0.20 times the thickness of the tube taken in a direction between the sides of the plate which face the negative electrodes. At least one side of each tube has a concave surface. The tubes are formed with integral rigid flanges formed by weld joints between the tubes. The flanges support the tubes and aid in shaping of the tubes.
