ABSTRACT:
A fiber structure electrode plaque for accumulators made from a needle felt web made of synthetic fibers which, after activation, is chemically metallized, and galvanically reinforced by being metal-plated. The needle felt web has a weight per unit area of between 50 and 150 g/m.sup.2 with a porosity of from 60 to 96%, the synthetic fibers having a diameter of from 10 to 30 .mu.m, and the length of the staple fibers amounting to from 20 to 40 mm. Over its whole surface, the needle felt web is needled from both sides and has a nominal thickness of from 0.5 to 1.0 mm.
