Abstract
An electrochemical element which contains a stack including two or more individual cells with positive and negative electrodes as well as separators in a housing formed from a metal sheet which is coated on the inside with insulating material. The output conductor lugs of each polarity are welded to a collector. The collector forms an external electrical connection of the electrochemical element. Those areas of the output conductor lugs and the collector which are welded to them, point towards the housing internal wall and are adjacent to the housing wall and are covered with a plastic film. The plastic film is adhesively bonded to the output conductor and to the collector with a silicone adhesive layer and is composed, for example, of polyimide.
