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.
