Patent ID: 7294432

Claim:
A battery, comprising: a battery case; an electrode assembly disposed within the battery case, said electrode assembly including at least a first electrode tab and a second electrode tab; a feedthrough pin having a substantially vertical segment and a laterally extending segment including a distal end; a battery cover coupled to the battery case; a headspace insulator having a top surface and a bottom surface, the bottom surface having a recess to receive the distal end of the feedthrough pin, the headspace insulator further having a detent located within the recess and configured to accept the distal end segment of the feedthrough pin and to hold the distal end of the feedthrough pin in place with an interference fit when the distal end of the feedthrough pin is received into the recess; and a feedthrough assembly, comprising a conductive ferrule and an insulating member, wherein the recess forms a receiving area for the distal end of the feedthrough pin such that the distal end of the feedthrough pin is locked into the receiving area of the headspace insulator to resist movement and wherein the distal end of the feedthrough pin is coupled to the second electrode tab.
