Abstract: Conductors for use in batteries, storage batteries, and solar collectors are produced by means of electrolysis. According to the invention, a method of this type for the production of an electrical conductor, which conductor comprises a copper-containing screen material, comprises the steps of using electrodeposition to deposit a copper skeleton on conductive parts of an electroforming matrix in an electrodeposition bath, and removing the deposited copper skeleton from the electroforming matrix, and if desired further growing of the skeleton, the screen material having a density of openings which lies in the range of 1-20,000/cm2 and allows of an open surface area which is larger than a defined minimum.
