A system for producing electrodes for lead-acid batteries is disclosed. An electrode that has been produced comprises at least one upper and/or one lower frame element as well as a lattice-shaped region that extends away from said upper or lower frame element and has a plurality of openings, the upper and/or lower frame element being of a greater thickness than the lattice-shaped region. Said system comprises the steps of: a) producing a profiled strip-shaped blank using a casting method in which the strip-shaped blank is formed, solely by means of said casting method, to have a greater thickness on one side in at least one of the regions which should eventually form the upper or lower frame element, than the thickness in regions which should eventually form the lattice-shaped region, and b) producing said lattice-shaped region with the openings in a subsequent expanded metal process.

The invention relates to a laminar textile material for covering a pasty active mass on a battery electrode. The invention further relates to a battery electrode having such a material, to a battery, and to a method for producing battery electrodes. Potential improvements of lead batteries are disclosed that are more practical than previously known solutions, and that stabilize the pasty active mass on the battery electrodes. A laminar textile material is disclosed to this end, comprising glass fibers and fibers made of a thermoplastic, e.g. polyester.

The present disclosure relates to a method for producing an electrode plate of a rechargeable electrochemical battery that includes producing a substantially flat lead grid having a plurality of grid bars and a plurality of window-like cutouts formed between the grid bars, introducing an active material into the cutouts and/or onto the grid bars of the lead grid, creating a pattern of slot-shaped depressions in the active material by mechanically impacting the lead grid provided with the active material, where the depressions extend to a depth from the outer surface of the active material. The present disclosure further relates to installation of an electrode plate in a rechargeable electrochemical battery.
