    Abstract: The disclosed embodiments relate to the design of a battery cell with multiple thicknesses. This battery cell includes a jelly roll enclosed in a pouch, wherein the 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 jelly roll also includes a first conductive tab coupled to the cathode and a second conductive tab coupled to the anode. The jelly roll is enclosed in a flexible pouch, and the first and second conductive tabs are extended through seals in the pouch to provide terminals for the battery cell. Furthermore, the battery cell has two or more thicknesses, wherein the different thicknesses are created by removing material from one or more of the layers before winding the layers together.

    Abstract: A portable computing device includes at least a base portion of a lightweight material that includes at least a wedge shaped top case having a trough formed at an interfacing edge thereof. The trough includes a raised portion having a first contact surface and a receiving area, and a bottom case coupled to the top case to form a complete housing for at least a portion of the portable computing device for enclosing at least a plurality of operational components and a plurality of structural components. The portable computing device also includes at least a lid portion pivotally connected to the base portion by a hinge assembly. In the described embodiments, the lid portion has a display in communication with one or more of the plurality of components in said base portion by way of or more electrical conductors that electrically connect the base portion to the lid portion.
