Abstract: An electrode cell manufacturing process may include forming an electrode sheet including an electrode material and an active material. A first plurality of electrode tab windows may be defined in the active material to expose first portions of the electrode material. The process may also include slitting the electrode sheet along a first line that orthogonally intersects the first plurality of electrode tab windows to define a first electrode strip including a first set of electrodes and a second electrode strip including a second set of electrodes.

Abstract: The disclosed technology relates to a busbar and thermal cut-off device (TCO) sub-assembly. The sub-assembly may be configured to be connected to a first battery cell and a second battery cell. The sub-assembly may comprise a first busbar configured to electrically connect the first battery cell to the second battery cell when the sub-assembly is connected to the first battery cell and the second battery cell. The sub-assembly may comprise a first TCO connected directly to the first busbar. The sub-assembly may not extend above a top surface of the first battery cell when the sub-assembly is connected to the first battery cell.
