ABSTRACT:
A method of making composite electrode for use in a storage battery or other accumulator comprises disposing on opposite sides of a metal support provided with throughgoing openings respective synthetic-resin layers adapted to form pockets for the active mass. The synthetic-resin layers, in the form of screens, fabrics, grids or the like, are ultrasonically welded through the openings of the metal support together by the simultaneous application of mechanical pressure and ultrasonic energy. The active mass is then introduced into the pockets formed by the synthetic-resin layers which may be covered, if desired, by fine-porous cover layers applied by heat and pressure so as to weld these cover layers to the first-mentioned synthetic-resin layers.
