ABSTRACT:
Described is a support for electrodes of primary or secondary electric cells, said support comprising an open-mesh, three-dimensional network structure composed of plastics threads coated unbrokenly with one or more efficiently conducting, thin metal coats and, to form the three-dimensional structure, being provided with humplike depressions and/or elevations which are distributed over its surface and in whose region the distance between the plastics threads is increased, wherein at least the outer metal coat of the plastics threads consists of a valve metal. Also described are electrodes comprising such a support and a process for producing the articles mentioned.
