Galvanic element for high stresses

A galvanic element, with a cathode, an anode, an electrolyte, a separator arranged between the anode and cathode and a housing which comprises a housing cup, a housing cover and a sealing element, the sealing element insulating the housing cup against the housing cover, having a thickness direction extending from the housing cup to the housing cover through the anode and the cathode, and a radial direction that is normal to the thickness direction,

• wherein the sealing element has a substantially U-shaped cross-section that opens toward the housing cover, wherein the sealing element has an inner sealing lip and an outer sealing lip displaced from one another in the radial direction;
• wherein the cathode is surrounded by a support ring defining a cylindrical wall in the thickness direction,
• wherein the separator further comprises a radial fastening region projecting radially at least over the inner sealing lip and a further portion bending substantially perpendicular to the radial fastening region, the further portion being parallel to the cylindrical wall in the thickness direction,
• wherein the further portion of the separator is clamped in between the housing cover and the inner sealing lip of the sealing element, and the inner sealing lip of the sealing element is clamped between the cylindrical wall and the further portion,
• wherein the sealing element has a periphery on top of the inner sealing lip comprising an annular fastening region, wherein the annular fastening region is normal to the further portion of the separator, wherein the sealing element is either welded or glued continuously along the entire annular fastening region to the separator.
