Abstract
The disclosed embodiments provide 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 resistance of the battery cell to mechanical stress may be improved by removing material from one or more of the layers to form one or more apertures within the battery cell and placing a mechanical support in each of the apertures.
