    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: Some embodiments provide a system that monitors a battery in a portable electronic device. During operation, the system applies a pulse load to the battery and determines an impedance of the battery by measuring a voltage of the battery during the pulse load. Next, the system assesses a health of the battery based on the impedance. Finally, the system uses the assessed health to manage use of the battery in the portable electronic device.

    Abstract: An outer cover of a pouch-style battery includes a nanoceramic coating. Constructing an outer cover including a nanoceramic coating may include forming a malleable layer, applying a sealing layer to an inside surface of the malleable layer, and applying the nanoceramic layer to an outside surface of the malleable layer. Fabricating an outer cover including a nanoceramic coating may further include applying a protective film to an outside surface of the outer cover, which may be removed shortly before or after installation of a battery cell for which the outer cover is manufactured. Fabricating an outer cover including a nanoceramic coating may also include applying one or more adhesive layers, for example an adhesive layer between the malleable layer and the sealing layer. An outer cover including a nanoceramic coating may be sealed around a battery-active-material assembly to form a pouch-style battery cell.

    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.
