Abstract: This electrochemical cell for a battery, comprises a first electrode of a first polarity, a first terminal of the first polarity, a second electrode of a second polarity, a second terminal of the second polarity, an envelope comprising two walls. The envelope comprises two first edges and two second edges forming an enveloping quadrilateral. The first terminal of the first polarity and/or the second terminal of the second polarity is disposed entirely within the enveloping quadrilateral. The two walls each comprise a metal base foil having a thickness of between 20 μm and 150 μm. The first terminal of the first polarity is arranged in a first corner of the enveloping quadrilateral and the second terminal of the second polarity is arranged in a second corner of the enveloping quadrilateral, different from the first corner.

Abstract: The invention relates to a battery cell comprising a bucket, a lid attached to the bucket, at least one first electrochemical bundle in the bucket, at least one first polarity collector.
The first polarity collector is integral with the lid and defines at least one first welding surface located away from the bucket, to which the electrical connection tabs of the first electrodes of the first electrochemical bundle are welded.
The cover comprises an upper part delimiting at least a first through opening located opposite the first welding surface in a direction of elevation.
The battery cell further comprises a sealing device attached to the cover and designed to seal the first through opening.
