Abstract: This electrochemical element for a battery, comprising 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, and a casing comprising a first wall and a second wall. The first wall and the second wall each comprise a base body of metal and an electrically insulating layer. The electrically insulating layer comprises either a plastic coating or a layer resulting from a surface treatment. Each of the base bodies comprises a base body edge. The edges of the base bodies are joined by a weld bead to form the casing. At the location of the weld bead, the base bodies are free of the electrically insulating layer.

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 ?m and 150 ?m. 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 present electrochemical element for a battery comprises a first electrode of a first polarity, a first connection member for the first polarity, a second electrode of a second polarity, a second connection member for the second polarity, and a casing comprising a first wall and a second wall. The casing comprises a first edge and a second edge which form an enveloping geometric shape having a corner. The first connection member and the second connection member are arranged completely within the enveloping geometric shape. The first connection member and the second connection member are arranged in a first corner of the enveloping geometric shape.
