    Abstract: This electrochemical assembly (8) comprises a first electrochemical stack (16), having first stack electrodes of a first polarity (162) and first stack electrodes of a second polarity (164). The first stack electrodes of the first polarity comprise first terminal tabs (18) of the first polarity and forming a first electric terminal tab stack (20). The electrochemical assembly (8) comprises a second electrochemical stack (22), having second stack electrodes of the first polarity (222) and second stack electrodes of the second polarity (224). The second stack electrodes of the first polarity comprise second terminal tabs (24) of the first polarity and forming a second electric terminal tab stack (26). The electrochemical assembly (8) comprises a first terminal (30) comprising a terminal portion (32) and a tab connection portion (34). The first electric terminal tab stack (20) overlaps the second electric terminal tab stack (26) and is electrically connected to the tab connection portion (34) of the first terminal via the second electric terminal tab stack (26).

    Abstract: An electrochemical cell comprising a first electrode separated from a second electrode by a shutdown separator. The first electrode can comprise a first current collector substrate having a first active material composite layered thereon. The second electrode can comprise a second current collector substrate parallel to the first current collector substrate. The second current collector substrate can have a second active material composite layered thereon. The first current collector substrate can have a first current collector tab extending from the first current collector substrate at a position along an axis parallel to a plane defined by the first current collector substrate. The second current collector substrate can have a second current collector tab extending from the second current collector substrate at a same position along the axis as the first current collector tab. A battery including the electrochemical cell and methods for manufacturing the battery are also described.
