Classification: CPC H  Y | IPC H

Claim 11:
12. 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, wherein the housing is characterized by a second side opposite the first side, a third side extending between the first side and the second side, and a fourth side opposite the third side; and
an electrode stack positioned within the housing, the electrode stack comprising:
a first current collector characterized by a first side facing the first side of the housing, a second side opposite the first side, a third side extending between the first side and the second side, and a fourth side opposite the third side, wherein the first current collector defines a first current collector tab along the third side of the first current collector, the first current collector tab extending towards the third side of the housing, wherein the first current collector tab is electrically coupled with the first terminal, and
a second current collector characterized by a first side facing the first side of the housing, a second side opposite the first side, a third side extending between the first side and the second side, and a fourth side opposite the third side, wherein the second current collector defines a second current collector tab along the fourth side of the second current collector, wherein the second current collector tab is electrically coupled with the second terminal, wherein:
the second current collector defines a first and second series of second current collector tabs distributed along the fourth side of the side current collector;
the first series of second current collector tabs is closer to the first side of the housing than the second series of second current collector tabs; and
a first spacing between each second current collector tab of the first series of second current collector tabs is greater than a second spacing between each second current collector tab of the second series of second current collector tabs.
