    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.

    Abstract: The disclosed embodiments relate to the manufacture of a battery cell. The battery cell includes a set of layers including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a pouch enclosing the layers, wherein the pouch is flexible. The layers may be wound to create a jelly roll and/or stacked prior to sealing the layers in the flexible pouch. A side fold is also formed in the pouch by producing a target temperature in the range of 55° C. to 75° C. at a side seal of the pouch prior to folding the side seal against the battery cell.

    Abstract: Cell stacks are presented that include binders for wet and dry lamination processes. The cell stacks, when laminated, produce battery cells (or portions thereof). The cell stacks include a cathode having a cathode active material disposed on a cathode current collector. The cell stacks also include an anode having an anode active material disposed on an anode current collector. The anode is oriented towards the cathode such that the anode active material faces the cathode active material. A separator is disposed between the cathode active material and the anode active material and comprising a binder comprising a PVdF-HFP copolymer. In certain instances, an electrolyte fluid is in contact with the separator. Methods of laminating the cell stacks are also presented.

    Abstract: The disclosed embodiments provide a battery cell which includes a set of jelly rolls enclosed in a pouch. Each jelly roll includes layers which are wound together, including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a first set of conductive tabs and a second set of conductive tabs. Each of the first set of conductive tabs is coupled to the cathode of one of the jelly rolls, and each of the second set of conductive tabs is coupled to the anode of one of the jelly rolls. At least one of the first set and one of the second set of conductive tabs extend through seals in the pouch to provide terminals for the battery cell.
