Abstract
A metallized synthetic resin fiber electrode structure is described, based on a nonwoven fabric, with a porosity of 85-96% and a fiber thickness of 10-30 .mu.m, determined, respectively, in the nonmetallized condition, wherein the nonmetallized nonwoven fabric is characterized by the following strength properties. The quotient of the flexural stiffness according to DIN 53 362 (cantilever test) and the square of the nonwoven fabric thickness according to DIN 53 855 ranges between 80 and 400 cN. The deformation of a sample stack in the 5th cycle under 200 N in the compression test according to DIN 54 305 amounts to 6-18 mm. The force required to obtain half the achieved deformation amounts to 30-70 N. Polypropylene needle felts are preferred having a metallic coating of 0.1-10 .mu.m, especially 1-6 .mu.m. The electrode structures according to this invention can also be manufactured with larger thicknesses and permit production of rugged electrodes having reproducible properties.
