Abstract

An electrochemical cell and method of making same are provided wherein the electrochemical cell includes a radial sealing function effected by the combination of a seal comprised of an amorphous polymer and a cell container wall having a stiffening rib on one axial side of the seal and a lip on the other side of the seal wherein the rib and the lip eliminate springback of the container wall upon removal of the external radial force establishing the compressive sealing forces.
