    Abstract: The disclosed embodiments relate to the design of a stacked-cell battery comprising a stack of layers, including alternating anode and cathode layers coated with active material with intervening separator layers. The stack includes a plurality of notches formed along one or more sides of the stack, including a first notch and a second notch, wherein each cathode layer includes an uncoated cathode tab extending into the first notch, and wherein each anode layer includes an uncoated anode tab extending into the second notch. Moreover, a common cathode tab is bonded to the cathode tabs within the first notch, and a common anode tab is bonded to the anode tabs within the second notch. The stacked-cell battery also includes a pouch enclosing the stack, wherein the common anode and cathode tabs extend through the pouch to provide cathode and anode terminals for the battery cell.

    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.
