Claim 0:
1. A battery comprising:
a housing comprising a first terminal disposed on a first side of the housing and a second terminal disposed on the first side of the housing; and
an electrode stack positioned within the housing, the electrode stack comprising:
an anode current collector, wherein the anode current collector is characterized by a first side facing the first side of the housing, wherein the anode current collector defines an anode tab along a second side of the anode current collector, the anode tab extending from the anode current collector in a direction normal to a direction facing the first side of the housing, and wherein the anode tab is electrically coupled with the first terminal, and
a cathode current collector, wherein the cathode current collector is characterized by a first side facing the first side of the housing, wherein the cathode current collector defines a cathode tab along a second side of the cathode current collector, the cathode tab extending from the cathode current collector in a direction normal to the direction facing the first side of the housing, and wherein the cathode tab is electrically coupled with the second terminal, wherein:
the cathode current collector defines a first and second series of cathode tabs distributed along the second side of the cathode current collector;
the first series of cathode tabs is closer to the first side of the housing than the second series of cathode tabs; and
a first spacing between each cathode tab of the first series of cathode tabs is greater than a second spacing between each cathode tab of the second series of cathode tabs.
