Abstract:
1. An electrochemical cell, comprising: a) a casing; b) an electrode assembly contained within the casing, the electrode assembly comprising: c) an electrolyte contained within the casing to activate the electrode assembly; d) a terminal pin passing through a feedthrough in a non-conductive relationship with the casing, wherein the terminal pin is of a second metal having a second melting temperature greater than the first melting temperature of the first metal, and wherein the terminal pin extends from a proximal terminal pin portion connected inside the casing to the current collector for the one of the anode and the cathode to a distal terminal pin portion residing outside the casing as a first terminal for the anode or the cathode; e) wherein the proximal terminal pin portion is joined to the connection tab of the current collector by a direct resistance weld, the weld comprising: f) wherein the casing is a second terminal for the other of the anode and the cathode not connected to the terminal pin.
