Patent number: 11417871Abstract: 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.

Patent number: 10418623Abstract: A method for manufacturing electrodes for lead-acid batteries includes producing a profiled strip blank in a casting process, wherein the casting process alone is sufficient to cause the strip blank to be formed of greater thickness on one side in a region corresponding to the upper frame element or the lower frame element than in another region corresponding to the meshed region; and producing the meshed region with the openings in a subsequent expanded metal process. In addition, an electrode produced by the method has an upper frame element, or a lower frame element, or both, and a meshed region extending away from the upper frame element, or the lower frame element, or both and having a plurality of openings. The upper frame element, the lower frame element, or both, is of greater thickness than the meshed region.Type: GrantFiled: March 22, 2013Date of Patent: September 17, 2019Assignee: Johnson Controls Autobatterie GMBH & Co.
