ABSTRACT:
An electrochemical storage device and a process for making the same has electrode plates of differing polarity which are stacked one upon the other. Each one of the electrode plates exhibits a metallized electrode structure and a current tapping vane which is resistant to bending and which is electrically conductively secured to a welding margin of the electrode structure. The same-polarity current tapping vanes of the electrode plates are electrically connected to a connecting strap extending parallel to the electrode plate stack and within the storage device housing. In order that, inter alia, the service life of the electrochemical storage device should be increased, the current tapping vanes disposed at the electrode structures are permanently shaped in accordance with their installation position essentially only outside the welding margin, in such a manner that in the installed condition they are free from mechanical stresses in the region of the welding margin onto the electrode structure.
