Abstract:
An electrochemical cell comprising an electrode assembly having a plurality of cathodes in which the plurality of cathodes is electrically connected together at a connection tab junction is disclosed. The junction preferably comprises a plurality of cathode connection tabs that are folded over each other to construct a junction that is mechanically and electrically robust. The junction is comprised of a plurality of connection tabs that each extend from a cathode. Each of the respective tabs is folded over each other to form a compact electrode junction having redundant connections. An elongated lead extends from the junction to provide an electrical connection to the plurality of cathodes. The junction is welded together such as by a laser, resistance or ultrasonic weld joint. The cathode junction is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

Claim (Index 14):
An electrochemical cell, comprising:\n a) a casing; b) an electrode assembly contained within the casing, the electrode assembly comprising:\n i) an anode comprising an anode active material contacted to an anode current collector, wherein an anode tab extending outwardly from the anode current collector is connected to the casing serving as a negative terminal for the cell; \n ii) at least a first cathode and a second cathode, the first cathode comprising:\n A) a first cathode current collector comprising a first bridge extending to spaced apart first cathode current collector first and second screens, the first and second screens each supporting a cathode active material, wherein a first landing strip extends outwardly from the first bridge, the first landing strip comprising a first landing strip lower surface spaced from a first landing strip upper surface with the first landing strip lower surface being closer to the first and second screens than the first landing strip upper surface; \n B) a second cathode current collector comprising a second bridge extending to spaced apart second cathode current collector third and fourth screens, the third and fourth screens each supporting a cathode active material, wherein a second landing strip extends outwardly from the second bridge, the second landing strip comprising a second landing strip lower surface spaced from a second landing strip upper surface with the second landing strip lower surface being closer to the third and fourth screens than the second landing strip upper surface; and \n C) a cathode plate extending to the first and second bridges, \n D) wherein the cathode plate is contacted by the first and second landing strip lower surfaces; \n E) a cathode lead extending from a cathode lead proximal portion to a cathode lead distal portion, wherein the cathode lead proximal portion is contacted to the cathode plate, and \n \n iii) wherein the anode is positioned in a facing relationship with the first cathode current collector first and second screens and with the second cathode current collector third and fourth screens; and \n iv) a separator residing between the anode and the first and second cathodes; and \n c) a feedthrough comprising a terminal pin of a glass-to-metal seal supported by the casing, wherein the terminal pin extends from a terminal pin proximal end to a terminal pin distal end, the terminal pin proximal end being conductively connected to the cathode lead distal portion with the terminal pin distal end being located outside the casing to thereby serve as a positive terminal for the cell; and d) an electrolyte contained within the casing to activate the electrode assembly.
