Abstract
The invention relates to a rolled electrode for a storage battery, wherein the electrode (10) is of substantially plate-like design and has a frame (12, 13, 15, 17) with a grid (16) arranged therein. A contact lug (14) for connecting the electrode to a battery pole is also provided on the frame (12, 13, 15, 17). Electrodes of this type are used, for example, in lead-acid storage batteries for vehicles, for example as a starter battery. The intention is to specify an electrode with improved electrical and mechanical properties and also possible ways of producing said electrode. To this end, the frame (12, 13, 15, 17) and/or the contact lug (14) in the electrode according to the invention have/has a greater thickness than the grid (16) arranged therein, at least in specific regions. A machine for producing such an electrode and a production method are also specified.
