Claim:
1. An electrochemical cell, comprising: a) a casing; b) an electrode assembly contained inside the casing, the electrode assembly comprising: c) an electrolyte contained in the casing to activate the electrode assembly; and d) a terminal pin of a second metal extending from a proximal pin portion to a distal pin portion, e) wherein with the proximal pin portion received inside the tubular portion of the coupler, a gap resides between the inner surface having the first inner diameter and an outer surface of the proximal pin portion, f) wherein the tubular portion is characterized as having been subjected to a magnetic pulse welding force so that a distal segment of the tubular coupler portion assumes a second inner diameter that is in direct physical contact with the outer surface of the proximal pin portion, but with a proximal segment of the tubular portion remaining at the first inner diameter greater than the second inner diameter, and g) wherein the distal pin portion extends outside the casing with the terminal pin being in a non-conductive relationship with the casing.
