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: Aspects of the present disclosure involve various battery can designs. In general, the battery can design includes two fitted surfaces oriented opposite each other and seam welded together to form an enclosure in which a battery stack is located. To form the enclosure, the two fitted surfaces are welded together along the large perimeter. Other swelling-resisting advantages may also be achieved utilizing the battery can design described herein including, but not limited to, the ability to modify one or more can wall thicknesses to control a pressure applied to the battery stack by the can, overall reduction in wall thickness of the can through the use of stronger materials for the can surfaces, additional supports structures included within the can design, and/or bossing or other localized thinning of surfaces of the can.

Abstract: The claimed invention relates to the design and manufacture of a battery cell including a cathode active coating (304) containing a first cathode active material and a second cathode active material with a lower first coulombic efficiency and a higher energy density than the first cathode active material. The battery cell also includes an anode active coating (308) containing a silicon-based anode active material and a carbonaceous anode active material. Finally, the battery cell includes a flexible pouch enclosing the cathode and the anode. Such blending of cathode and anode active materials may increase the energy density of the battery cell while mitigating the loss of capacity caused by the reaction of the silicon-based active material with lithium during initial charging and discharging of the battery cell.
