The invention relates to a device (1) for accumulation of electrical energy comprising a substantially cylindrical winding of strips (2, 4) at least one strip (2) of which being a strip conductor (2) of electricity, this device (1) being defined transversally by a substantially cylindrical lateral face (1A) and longitudinally by two opposite end faces (1B, 1C) which each contain an edge (2B, 2C) of the said strip conductor (2) of electricity, this device being characterized in that at least one of the edges (2B, 2C) of at least one strip conductor (2) of electricity contains a plurality of teeth (5) disposed in such a way that on at least one of the end faces (1B, 1C) of the device (1) they form at least one set in which they are substantially superimposed in a predetermined direction, approximately perpendicular to a plane tangent to the cylindrical face (1A) of the said device, in such a way as to constitute a group of elements of electrical connection to a terminal (6) and in which each element (5) extends itself in continuity with the strip conductor (2) of electricity which comprises it.
A device for accumulating electrical energy comprising a substantially cylindrical winding of strips (2) at least one of which is an electrical strip conductor, this device (1) being defined transversally by a substantially cylindrical lateral face (1A) and longitudinally by two opposite end faces (1B, 1C) which each contain an edge (2B, 2C) of the said electrical strip conductor (2), this device being characterized in that at least one of the edges (2B, 2C) of at least one electrical strip conductor (2) includes a plurality of teeth (5) disposed in such a way that on at least one of the end faces (1B, 1C) of the device (1) they form at least one set in which they are substantially superimposed in a predetermined direction, approximately perpendicular to a plane tangent to the cylindrical face (1A) of the said device, in such a way as to constitute a group of elements of electrical connection to a terminal (6) and in which each element (5) extends in continuity with the electrical strip conductor (2) which comprises it.
A method of producing a device (1) for accumulating electrical energy, on the one hand, defined transversally by a substantially cylindrical lateral face (1A) and longitudinally by two opposite end faces (1B, 1C) separated by a distance (D), and, on the other hand, obtained by winding strips (2) at least one of which being an electrical strip conductor (2) whose initial width (L), defined between two lateral borders (2D, 2E), is greater than the distance (D) that separates the said opposite end faces (1B, 1C), this method being characterized in that it is at the latest after the strips (2) have been wound that the teeth (5) are achieved by cutting notches (7) in at least one of the two lateral borders (2D, 2E) which determine the initial width (L) of at least one electrical strip conductor (2).
