    摘要： 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.

    摘要： 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.

    摘要： 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.
