The invention relates to a method for producing electrodes (14) for lead-acid batteries (30). An electrode (14) that has been produced comprises at least one upper and/or one lower frame element as well as a lattice-shaped region (12) that extends away from said upper or lower frame element (9, 10) and has a plurality of openings, the upper and/or lower frame element (9, 10) being of a greater thickness (D) than the lattice-shaped region (12). Said method comprises the steps of: a) producing a profiled strip-shaped blank (2) using a casting method in which the strip-shaped blank (2) is formed, solely by means of said casting method, to have a greater thickness (D) on one side in at least one of the regions (3, 5, 7) which should eventually form the upper or lower frame element (9, 10), than the thickness in regions (4, 6) which should eventually form the lattice-shaped region (12), and b) producing said lattice-shaped region (12) with the openings in a subsequent expanded metal process. The invention also relates to an installation for producing electrodes for lead-acid batteries, an electrode, and a lead-acid battery. |
