    Abstract: Batteries according to embodiments of the present technology may include a first battery cell including a first current collector. The batteries may include a second battery cell including a second current collector. The second battery cell may be vertically aligned with the first battery cell, and the second current collector may be positioned adjacent the first current collector. The first battery cell and the second battery cell may be electrically coupled together so the first battery cell and the second battery cell transfer current through the cells between the first current collector and the second current collector. The batteries may also include a patterned coupling material disposed between the first battery cell and the second battery cell and joining the first current collector with the second current collector.

    Abstract: A battery cell includes a cathode casing forming all or a majority of the external can of the battery cell. The battery further includes an anode tab covering at least a portion of a face of the battery cell and an insulating layer for electrically isolating the anode tab from the cathode casing. A plurality of such battery cells may be arranged within a battery pack in contact with each other, and may be held in compression. A conduction enhancement layer may be applied between the anode tab of a first cell and the cathode casing of a second cell within the battery pack. One or more heat dissipation elements may be arranged within the battery pack, in contact with the battery cells.

    Abstract: The disclosed embodiments relate to the manufacture of a battery cell. The battery cell includes a first set of layers including a cathode with an active coating, a separator, and an anode with an active coating. The separator may include a ceramic coating and a binder coating over the ceramic coating. During manufacturing of the battery cell, the layers are stacked, and the binder coating is used to laminate the first set of layers within the first sub-cell by applying at least one of pressure and temperature to the first set of layers. In addition, uniform pressure is applied to the cell stack to laminate the first and second sets of layers.
